Bringing some of the benefits of electrical power to our off-grid home has been a hit-or-miss affair.
Today, with the help of a local expert on off grid home solar power and alternative energy systems, we have the best of both worlds. Our simple home solar power system is comprised of four basic components: a solar panel, a charge controller, two 6-volt golf cart batteries and a small inverter. The cost of this complete solar system, in today’s pricing for the components, was less than $1000.
About the shadows on the panels: Our solar placement is the best we could manage since our home is nested among trees. We have a single solar panel mounted on the roof of our home: a 123 watt Sharp Photovoltaic Module, model 123UJF. We use a Trace C12 Charge Controller which automatically adjusts the amount of power running into the battery. The final piece of the system is a small inverter which converts the 12 volt DC power into 120 volt AC power. An alternative energy system can be used to provide electric power to any number of electric devices, such as appliances, tools and computers. This is a DC powered refrigerator, the same size as a conventional chest freezer (4’ wide). This is our Vers sound system which lets us use an iPod or direct cable from an iPhone or computer to deliver a rich sound while drawing relatively little power.
These are the principle applications we use which are provided by the solar power system described above.
Originally from Long Island, NY, Greg Seaman founded Eartheasy in 2000 out of concern for the environment and a desire to help others live more sustainably.
Yes, there are certainly business opportunities in this field – renewable energy is ready for wide use in the general population. In a simple, inexpensive system like ours, I find the best solution is to keep a spare inverter and charge controller. Greg, We are building a 700 ft off grid home that will use solar for a chest freezer, some lighting, an energy efficient ceiling fan as necessary, charging some electronics such as laptops and flip cell phones, run an LED HDTV a few evenings a week, etc. Yes, it is getting to where independent power systems are viable for small applications like homes and small communities. Calculate all your anticipated electric needs and take the list to a solar power dealer or an alternate energy provider.
An off-grid solar (photo-voltaic) electric power system is an ideal prep for modern survival in that it can partially or totally relinquish you from dependence upon other systems, which themselves are vulnerable to disruption or breakdown. Although there is much more to know regarding the proper design and construction of an off-grid solar power system, the following basic essential elements should give you a basic summary of the main components involved. Today’s typical residential solar panel may contain enough individual cells to produce about 250 watts (although there are lots of different sizes). For example you might want enough power to run a refrigerator, maybe a chest freezer, a number of lights, along with enough left-over energy to occasionally run a washing machine, kitchen appliance, radio or TV, and a computer, etc. Lets say the worst case scenario for acquiring sunlight is during the middle of winter, and depending on your geo location – with 4 hours of good sunlight to provide electrical charging capability through your solar panels. 3,000 (watts) divided by 4 (hours of good sunlight) equals 750 watts of solar panel power capacity to absorb and convert 4 hours of solar energy into 3 kWh of electricity. The charge controller is the electronic device that is between the solar panel array and the battery bank (the batteries store the energy). It is intelligent in that it automatically adjusts depending upon the load on the system, and the state-of-charge of the batteries – versus the amount of available power from the solar panels at any given moment (at least the better ones do this).
Since you do not consume all of your daily energy requirements during only daylight hours, an off-grid system will store the energy that is collected during daylight into a bank of batteries to be used when the solar panels are no longer in the sunlight. An additional consideration for the overall solar power system is the number of backup days that you may want to have energy in reserve – during times when the sun is covered by clouds during periods of bad weather. You will need this inverter unless you have special appliances and lighting to operate on DC power.
There are cheap inverters out there which I caution against for several reasons, including the ability to handle short-term high current loads from motors and compressors starting up (refrigerators and freezers for example).


Lithium or calcium cells are safe for indoor use but have a much shorter life than lead acid. Make sure you get quality solar panels and have them installed by verified quality installers using high quality connections. If your house catches fire your local fire department maybe very hesitant in fighting the fire if you have solar panels installed. If you’re planning on a system with more than 1000 watts in panels I strongly suggest not using 12v for your battery bank.

I wanted solar, but there was not a place on my roof where it would look good and avoid shading.
An assessment is a study of the potential installation that you will live with for the next 40 plus years. Solar site assessments are designed to provide you with site-specific information about how a solar system can address your energy needs.
We service and repair all of the systems we install including: solar electric, solar domestic hot water, boilers, tankless water heaters, gas appliances and generators.
In an off-grid context, backup generators make sense for extended sun-free days, occasional large loads for equipment or entertaining guests. Over the years we’ve tried some very simple approaches to lighting and small battery recharging for our flashlights, such as hauling a 12 volt car battery to a small rural school about a half mile away every time it needed to be topped up. Our basic solar powered energy system provides more electricity than we expected, it has been very reliable and maintenance-free, and it is almost entirely hidden from view.
The refrigerator has not been off for over two years, which is pretty impressive considering we live in the Pacific Northwest where the short winter daylight hours provide minimal solar exposure for the panel.
The panel is equipped with a permanently attached junction box for ease of installation of wires and conduit. The refrigerator draws 40 watts of power and can be converted to a freezer by replacing the thermostat. The costs and options for solar arrays, inverters and charge controllers keeps dropping, and I am not an expert on recommending systems.
Some suggest isolating the charge controller in a metal box or can, you would have to do a little research to find the best solution. I am not an expert in solar technologies, and relied on a local solar installer for advice. We managed for years with just the one panel, today we have three panels and a 30 amp charge controller. Our suggestion is to go with a chest style, DC powered, with easily replaceable thermostats.
A typical solar panel is made up of an array of many small individual solar cells, made of crystalline silicone, each connected together to provide a usable amount of total power.
The result is a unit of energy which is required to power that device – power multiplied by time. Better inverters provide pure sine wave AC power and will not damage your appliances (or electronics). You maybe surprised by the number of solar arrays that are sitting on rooftops which are faulty and the owners can’t afford to have them repaired. They performed well, although I had to keep them in a shed outdoors – with ventilation. Grid tie systems are for Yuppies who drive Priuses and I hear they are disabled during an outage (for the safety of utility crews). This leads to a lot of people leasing units, which is paradoxically reducing the selling potential of the abode, should they need to move. We specialize in consultation, creative design and installation of solar electric, solar thermal and unique heating systems. The documentation from a solar energy site assessor will determine a suitable location for your system and give an overview of the options available relative to your existing conditions. Next Step built our system under terrible winter conditions, and it has run flawlessly since commissioned on February 11, 2010, and produced power beyond our expectations.” - J. In certain conditions, by combining the radiant heating and domestic hot water into one system, a person may save a considerable amount of money compared with using two separate systems for heating and hot water.


By designing a smaller system to meet your normal day-to-day needs and including backup power for occasional use, you can save significantly on your system cost.  Backup generators are also common in grid connected homes for customers that wish to have energy security of automatic backup generation in the event of a power failure. All Sun Frost refrigerator models are available in 12 and 24 Volt DC and 120 and 240 Volt AC versions.  For more product details please visit the Sun Frost. A solar panel on the roof with a few wires leading to a small battery bank powers my laptop, and a radio mounted on a tree for receiving the wireless broadband signal. Two boards are lag screwed into the roof and the solar panel is bolted to the boards using wing nuts, so it’s easy to lift if maintenance is required.
But we live in a beautiful forested area and I value the tress more than 100% efficiency in solar gain. You’ll get better advice from your local solar provider who will know what options are available in your area, as well as the ideal configurations.
You can get more information from forums on the web, where no one is selling you their system. You know what, I am thinking of collaborating with Eartheasy once i get back to Nigeria next two yrs to start developing individual power unit completely independent of the National Grid. We have provided service for over thirty years to the greater Chippewa Valley region of Western Wisconsin. These indirect water heaters can easily be incorporated with a gas or wood boiler and are a standard feature of our solar domestic hot water systems. The automatic damper control makes the unit extremely safe and easy to operate from the comfort of your home. They feature low noise and vibration design and are very fuel efficient compared to other manufacturer's products.  These units are available in 120 or 240 Volt output to power a full range of electrical devices.
But we didn’t want to lose the feel of our simple home by bringing in a large generator and the jugs of gas needed to run it, and the prospect of setting up a wind turbine or solar array seemed expensive and a technological eyesore in a natural setting. The system also provides enough energy to charge several small power tools, run our home sound system and, amazingly, power a full-size chest refrigerator year round.
If there were a major solar loss I might top the tree, but our system provides for our needs and so we will live with the shadow, for now at least.
We can see that if the light is red we should reduce our power use, and if the light is green then we have the power needed to charge or run additional devices. Very low wattage, runs off a single 127 watt panel, has been running steady for over 4 years. It is a shame that in Nigeria, there is frequent blackout inspite of the windfall from crude oil, large water bodies which can be damed, or even generate power from Gas that is been flared to the atmosphere in the refineries. The ideal solar installation, of course, would have no shadows crossing the panels at any time. It comes with two cables, red and black, with alligator clip ends for gripping to the battery posts. Over time we may expand our system by adding more batteries for storage, and eventually a second solar panel or small wind turbine. After talking to a solar distributor, we realized we needed 24V, the 1500 W of solar and a different invertor. We sprang for a new propane fride, it costs about a dollar in fuel a day and yes, it is much smaller that an average american fridge but it’s better than a cooler. In choosing which size inverter to buy, we calculated how much power was available to our system and what devices we wanted to run.
Lithium Ion batteries are way too expensive for this application, although that may change.
In calculating power needs, it is important to add the power requirements when two or more devices are running simultaneously. By the way, I am an agric engineer and u know that solar energy utilization in engineering or agric has the sky as its limits.of water.
