The three major component of an off-grid solar power supply system are the solar panels, battery, and inverters. The panels themselves may be either monocrystalline, comprising of a single crystal-wafer, or polycrystalline, comprising of many small crystals. The suna€™s energy stirs up the tiny electrons inside the panels, and in the process, generates electricity. The power produced by solar panel and stored in the batteries are DC (direct current), but the power from the grid that lights up the house and on which appliances run is AC Alternating current).
The availability of power depends on a large extent to the size of the panels and the storage capacity of the batteries. A big factor that may either promote or impede the widespread adoption of solar panels is the cost. Solar panels offer an independent source of energy supply that would make the home or premises self-sufficient.

Homeowners have several choices when it comes to converting the sun’s abundant energy into electricity. These systems can also be used to heat swimming pools and provide hot liquid for radiant space heating. Solar water heaters share some of the same pros and cons as PV systems.
Financing theA costs associated with purchasing a solar energy system may be made easier through an Energy Efficient Mortgage (EEM) or a number of other options. The catch for these EEMs is that, in order to qualify for them, your house must be rated for its energy usage. One final condition is that your proposed improvements must be considered a€?cost effectivea‚¬A? by EEM standards. FHA EEMs exist to provide financing for homeowners who seek to implement energy-efficiency improvements. VA EEMs are available to qualified military personnel, reservists and veterans for energy-efficiency improvements when purchasing an existing home.
Fannie Mae is partnering with utility companies to provide low interest, unsecured consumer loans to utility customers for the purpose of installing residential energy efficiency improvements. Freddie Maca€™s programs are similar to Fannie Maea€™s, they encourage energy efficiency by providing specific criteria for energy efficient mortgages (EEMs) that Freddie Mac is willing to buy on the secondary market. Title-1 these second mortgages help finance solar projects that would not otherwise qualify under the 1st mortgage. The energy star financing program works with lenders to provide special financing for buyers of Energy star a€“ rated homes.


Solar panels, which draw energy from the sun, are now the most popular among such options, owing to its relative simplicity and consistency. In an advance system a generator and monitoring devices maybe used to provide an emergency backup AC supply. Monocrystalline cells have higher efficiency than polycrystalline cells, but costs higher as well.
This electricity is send to the charger, which maximises the power received and charges the batteries. The inverter converts the DC from the solar panels and the battery to AC and feeds it to the wires.
A monitor reveals the quantum of power consumption, and the power available in the batteries. The only thing required with the panels is place it to receive maximum sunlight exposure, and adjust the tilt depending on seasonal changes.

Learn about the different solar power options for your residential property.Photovoltaic (PV) SystemsA solar power system uses photovoltaic (PV) panels to convert the sun’s energy into electricity.
One of the obvious disadvantages is that the water heater must be connected to the residence's plumbing system rather than its electrical system.
Financing these costs may be made easier through an Energy Efficient Mortgage (EEM) and a number of other options. Obtaining the ratinga€”which ranges from 1 to 100 and scores everything from insulation to the type of appliances you usea€”costs several hundred dollars. Basically, this means that the resulting monthly savings in energy bills must be greater than the added monthly costs of the EEM.
Essentially they increase purchasing power by permitting lenders to increase the borrowera€™s income by a dollar amount equal to the homea€™s estimated energy savings.
Lenders are allowed to add 100 percent of the cost of the improvements to an already-approved mortgage loana€”provided that the costs dona€™t exceed $4,000 or five percent of the value of the home, up to $8,000, whichever is greater.
You also probably know, however, that once its installed your monthly energy bill will be a fraction of what it once wasa€”and that, in the long run, youa€™ll likely end up saving money. The residential Energy Efficiency Improvements loan program provides a below-market interest rate and promotes a bundled approach to efficiency upgrades, solar, water and space heaters as well as photovoltaic power systems (on and off grid) are eligible technologies for this loan program. These loans allow home buyers to purchase homes with mortgages 10% to 24% higher than they would have qualified for if their home were not energy star rated. The battery stores the power for actual use, ensuring that power is available even after sunset or on cloudy and rainy days.


The inverter also manages the entire system, coordinating the charge controller, the batteries, the AC panel, and also the generator, if included. The availability of a generator would allow provide backup AC power, useful to charge the batteries when the capacity becomes low, owing to the solar panels producing insufficient electricity. It may also be necessary to wipe the panels frequently, to remove it of dust or snow, which may impede the sunlight from penetrating. In remote locations, and places where chances of grid breakdowns are high, solar panels are a superior option in its own right. Conventional EEMs are offered by lenders who sell their loans to Fannie Mae or Freddie Mac. This means that the homeowner has to keep on making significant investments on a periodic basis. Moreover, the Fannie Mae loan is adjusted so that the value of the energy-efficient measures is reflected in the overall home value.
FHA section 203(b) 203(k) 221(d) 234(c) 203(h) loans may be used for both purchases and re-finances.
Electricity from the grid normally offers about three times the power for the cost that solar panel system would attract, and save the hassles of battery maintenance However, most countries subsidise the cost of solar panels and systems, which makes it cost effective.
This extra electricity might be sold to a utility company and delivered to other customers through the electrical grid in an approach called “net metering.”Thermal Solar SystemsFor homeowners who can’t afford PV solar power systems to generate electricity, a thermal solar water heater provides a less-costly alternative. These same materials reverse the effect in warm weather.Other passive solar devices, techniques, and systems include engineered roofing, climate-appropriate ceiling and wall insulation, and thorough air sealing.
Plus, the final HERS report will suggest measures that are likely to make the biggest improvements in your homea€™s energy usage.
In the UK, off-grid systems may even be a source of income, as the 'feed-in tariffs' scheme pays the solar panel owner for electricity produced from renewable sources, even when the electricity is not fed back into the national grid. For instance, in summer months, most solar systems waste the solar energy produced, and in contrast, during cloudy or rainy days, the power produced may be inadequate. Storage requires investing in powerful batteries, which remains too costly to become viable. If you can choose this option, ask for details about the sources of renewable energy available.If you live in a deregulated area with competitive market options, you likely have a choice of electricity providers that offer renewable energy options.
