The sun has been used for drying clothes and growing food for thousands of years, but only recently has the sun been used for solar power. Concerns over pollution, environmental degradation, and resource depletion have led to an increasing awareness of the importance of developing solar energy.
Just the tiny fraction of the sun's energy that hits the Earth (around a hundredth of a millionth of a percent) is enough to meet all our power needs many times over.
In fact, every minute, enough energy arrives at the Earth to meet our demands for a whole year - if only we could harness it properly. There are three ways to harness the sun's energy for use in our homes: solar cells, solar water heating, and solar furnaces. Enough power can be generated to run a 100W light bulb from just one square meter of solar panel.
Solar furnaces use a large array of mirrors to concentrate the sun's energy into a small space to produce very high temperatures. Once solar panels are installed, they produce energy without generating waste or pollution.
Solar electric generation is economically competitive where grid connection or fuel transport is difficult, costly or impossible. Once the initial capital cost of building a solar power plant has been met, operating costs are low when compared to existing power technologies.
They are applicable for low-power uses such as solar powered garden lights and battery chargers. A solar panel saves approximately 0.7 pounds of coal per kWh, or 2 pounds of carbon dioxide per kWh.
Over its 35-year expected life, a 10 kW system will provide CO2 reduction equivalent to planting 1450 trees. For larger applications, many photovoltaic cells are needed, corresponding to high investment costs and large land requirements.
The cost effectiveness of a solar energy system is dependent upon the location and climate. About one in three Solar Choice customers are asking about energy storage for solar power, but few have a clear idea of how much battery capacity they need. The list below presents the most popular uses of energy storage, sorted in descending order from greatest degree of energy independence to lowest degree of energy independence. Peak time independence: Install a system large enough to cover your electricity usage when grid electricity is most expensive. Energy storage as emergency backup: Install a small energy storage system to be used mainly in the event of a short power outage.
Choosing the right energy storage system capacity can be significantly more complicated and subjective than deciding on the right solar PV system size – mainly because of the greater number of variables involved. Solar Choice is in the process of developing a tool that will help our customers to get an estimate of the right energy storage system size.
Amount of energy storage available at the beginning of the day depends on battery state of charge from the night before. If it is impossible for the solar-plus-batteries system to meet 100% of demand, battery power is prioritiesed for use during peak & shoulder rate times. Electricity consumption level and pattern do not change between months and seasons (admittedly a big assumption). In this instance, the solar energy system is too small to both meet electricity demand and charge the batteries – even for peak demand.
Black line indicates electricity consumption, yellow line indicates solar system power output, purple line indicates battery state of charge (right axis), blue bars indicate solar power into battery, red bars indicate solar export to grid, orange area indicates self-consumed solar, purple area indicates electricity demand met by storage, and grey area indicates electricity demand met by grid. This example is the same as Example 1, except for a larger solar system – 10kW instead of 5kW. Without an energy storage system, a typical 7kW solar system would send about 70% of the electricity it produces into the grid for this household on the average day. The table below shows that the optimal battery size for this home would be about 15kWh, which allows for self-sufficiency and near 100% battery capacity utilisation in the peak of summer. On the back of the success of our informative and impartial Solar Quote Comparisons, Solar Choice is currently in the process of developing an online comparison platform for energy storage solutions – for retrofit and brand new installations.

In your analysis, your third example of an energy efficient household consumed 15kw per day.. Why is it still common practise to have either multiple days worth of power stored in battery banks and or to augment pv with a gen set when increasing the PV array and adding another charge controller is a more cost effective solution? If I’m understanding you correctly, you bring up a very interesting point – why not just install more PV (which will still generate some power even on a rainy day) rather than installing pricey batteries? Thanks again for your thoughts – this is something that we will certainly bear in mind for future analysis – especially when our research concerns going off-grid or achieving a high level of energy independence! A mostly wild-guess would tell me than I need at least a 25kWh battery storage which would still be “wasting” a lot of generation to the grid during summer?
There will be an announcement when our tool becomes live, if you want to join our mailing list (you’ll find a signup field to the left of this page). By our estimates, 20kW solar and 40kWh of storage would allow you daily energy independence on average and in summer.


Hope this helps – happy to try to help you out with further details if you have more questions. You can earn up to ?8,080 through the Government's feed-in tariff and save 50% on your electricity bills.
Fill out the form above to compare solar panel prices from installers in your area or read our guide to solar panel costs below. The chart below shows the plummeting costs of a typical 4kW solar system over the last few years. While solar costs are likely to fall slightly in the future, we recommend installing as soon as possible to benefit from low prices and cash in on the government’s Feed-in Tariff. Once your solar panels are installed and registered for the Feed-in Tariff, you lock in that tariff rate for the full 20 years of the payments.
Step 1 - Click your location on the map below to get your FREE quote.Step 2 - Once you answer a few simple questions, compare quotes in your area to find the best deal! Firstly, the government pays you for the electricity you generate and use, this typically adds up to about ?168 per year for an average 4kW panel.
You will also save on your energy bills because the electricity you use when your panels are in use is free. A single resident and a couple will use about the same amount of energy (3,300kW per year). Because of the way the Feed-in tariff works the more energy you produce, the more you get paid. The UK Government launched Green Deal in 2012 – a financing mechanism to help people pay for energy-efficiency improvements to their home such as insulation, glazing and microgeneration.
You repay your provider over time through your electricity bill - your electricity supplier passes payments directly to your Green Deal Provider. While south-facing roofs are ideal, east and west-facing rooftops only produce 15% less electricity. It should only take a couple of days, and you will be able to generate electricity the day after your installation is completed. Having a panel should ensure huge energy bill savings as prices look set to soar for the foreseeable future.
It also means that you and your family will be protected if there is an energy shortage, because you won’t be relying on gas or electricity companies, just the sun. The Feed-in tariff lasts for the first twenty years of your installation, earning you about ?8,000 over that period. Energy efficiency is often on the top of most property hunters' lists so it is more than likely that, if you want to sell your house, buyers will appreciate the energy savings of your solar PV panels. Solar panels are low-risk because they don’t have any moving parts apart from the small inverter. However, most PV installations come guaranteed for the first 25 years, and it’s widely acknowledged they last another 25 after that. They will install your solar panel properly and to industry standard, as well as providing a guarantee.

We can supply you with a steady stream of highly relevant enquiries, all of which have been verified with a phone call. Americans who want to install solar panels on their houses are having to pay less than ever before, a new report has found.
Since 1998, installed system prices have been falling thanks to reductions in the costs of solar energy that do not include the panels themselves: inverters, mounting hardware, labor, permitting and fees, customer acquisition, overhead, taxes, and installer profit. The steady drop in costs have helped to enable a steep increase in the pace of installation over the last several years. The soft costs, or non-hardware prices, can be influenced by local, state, and national policies. State of The Transition, July 2016: Might the fossil fuel industries implode faster than the clean energy industries can grow to replace them? Resilience is a program of Post Carbon Institute, a nonprofit organization dedicated to helping the world transition away from fossil fuels and build sustainable, resilient communities. There are some solar powered systems that utilize heat energy while others transform the light energy into electricity.
This article takes a look at the factors that come into play when considering how to choose the right amount of battery capacity for your solar-plus-storage system, using some specific examples examining the case for installing energy storage in Sydney.
While this may be a popular aspiration, taking your home or business off-grid is more often than not financially impracticable or just not possible to do with solar-plus-storage alone (especially if you have limited roof space for panels).
During the winter (and possibly autumn and spring) you’ll have to draw power from the grid to meet deficits. If your usage is higher, the outlay for a system that will meet your daily needs will also be more substantial; you may wish to look at ways to reduce your electricity consumption, or consider a lower degree of energy independence.
Examples of these patterns can be seen in the graph below; they are also discussed in further detail in this article. If, for example, you are currently exporting lots of solar to the grid at low feed-in tariff rates, you may want a larger amount of storage capacity to capture it.


This tool will soon be available to the public, but for now we have published some examples from Sydney below.
This means that the battery will only have a charge in the morning if there was solar electricity remaining from the day before (after being used to run appliances and charge batteries). Furthermore, a battery bank larger than 10kWh would probably not ever be fully charged on solar alone – the home would need to charge it with the grid at night in order for its full capacity to ever be utilised. With the larger solar array it is possible to achieve a high degree of energy independence with 15kWh or 20kWh of battery storage.
In this case, the goal of sizing the energy storage system would be to absorb the excess solar power for later use (without energy storage the solar capacity should be reduced to 1.5-2kW for optimal financial benefit). If the battery’s size were in increased to 20kWh, however, it would not be possible to charge it using solar alone, so about 25% of its capacity would never be used unless the household charges using the grid or with a generator.

I found it helpful, however I was wondering why with pv becoming so cheap does the model for energy storage not change to reflect this shift? For winter, you’d still be getting about 40-50% of your electricity from the grid unless you cut your electricity consumption then. The cost of solar panels has reduced by 70% in the past few years due to the technology maturing and mass market production.
In 2016, prices will rise slightly due to a recent EU ruling meaning that installers will have to pay the full 20% VAT on solar panels. As a result, the sooner you install, the higher the Feed-in Tariff rate your solar panels will qualify for and the more you will earn.
The government pays you for both the energy you use and the energy you don’t use (Feed-in tariff).
This table shows how much you can earn and save over time based on a 4kW system on average. A family with two children will use between 3,300kW and 4,500kW per year so will need a bigger panel. Installation and materials are not charged for up front, but repaid directly through the savings in your energy bills. Your repayments won’t exceed the savings you’re making on household bills, so you essentially make your repayment without feeling the pinch. You simply hand over the remaining charge – and all that valuable energy efficiency – to your buyer. If you are interested in becoming part of our supplier network please get in touch, we'd love to hear from you. This graph shows shows the growth of total installed solar capacity since 1998 (along with the sample).
Countries like Italy, Australia, and Germany have generally incentivized solar adoption through long-term policies, which have in turn helped to reduce soft costs. You will likely have to rely on the grid as a backup if there is a multi-day spate of bad weather during which your solar panels haven’t managed fill up your battery bank. Please note that these results are rough estimates, and should not act as a substitute for recommendations based on your individual circumstances. 7kWh is probably a good battery bank size to have because it strikes a balance between utilisation of excess solar and not oversizing the battery. However, in order for this home to achieve full self-sufficiency on the average day, it would probably be necessary to shift more electricity consumption to daylight hours and try to reduce their overall usage as much as possible (possible through simple energy efficiency measures).
We will also let you know when our energy storage system sizing tool is available on our website. Green Deal replaces the Carbon Emissions Reduction Target (CERT) and the Community Energy Saving Programme (CESP). Interest is charged on these repayments but remains fixed for the duration of the repayment schedule. In fact, residential PV systems installed last year in Italy, Australia, and Germany are nearly 40 percent lower than in the U.S. Installing a larger battery bank would only be worthwhile if the home had a larger solar array.
Alternatively, if you filled out the inverter capacity to a full 10kW of solar, that would afford you roughly 50% energy independence on average and roughly 65% independence in the summer (without sending too much solar into the grid).
First of all your home will need to be assessed for eligibility, so call the Energy Saving Advice Service on 0300 123 1234 to arrange an assessment with a local Green Deal representative. Be aware that Green Deal Providers set their own rates of interest, so it’s worth getting a few quotes before you settle on your provider. Once assessed - and if approved - you can take your personal Green Deal report to any registered Green Deal Provider, and if they can they’ll fund and carry out the work for you. These costs represent approximately half of the total installed cost of residential solar systems, so having the right policies in place at all levels of government remains the greatest opportunity for cost reductions, which Climate Progress discussed last month. And in California, PV system prices have decreased by an additional 10 to 15 percent just within the first six months of 2013 — leading the report authors to suggest that PV price reductions in 2013 are on pace to match or exceed recent years.
