A home solar power system is a very good way to generate free electricity from sunlight and lower your monthly utility bills. You can now reduce or even totally replace the power you buy from the local electricity company with home solar panels which are much more efficient and less expensive than they were even 10 years ago.   A great application of these solar panels is a   do it yourself solar charger .

The newer types of solar panels are greatly improved in many ways and, with little maintenance required of the homeowner, will provide decades of use.   The primary way these home solar panels have been improved is in the area of efficiency converting the sun’s energy into electricity.   Modern solar panels can achieve nearly 20% efficiency and so you will not require as many panels to produce the same amount of power as you would with older panels.   Because of this, you will not need as much space for the solar panels and installation costs will be much lower.   Homeowners with limited roof space will especially appreciate this benefit.   Previously, such homeowners could mount only as many solar panels as could fit on their roof and thus they may have been able to produce only a portion of the electricity needed.   Today they can meet their energy needs by generating more power with the same amount of roof space.

Another advantage to newer solar panels is they are more tolerant to orientation.   In order to produce maximum power output, older home solar panels had to be pointed due south.   This gives the panels access to sunlight at a direct angle for the most time per day. Because of the severe angle of the sunlight, these older panels would generate significantly less power during the day, just because the house didn’t have a side facing due south.   For the many people with houses that don’t have a southern facing side, these new panels are great news.   If you want to build your own solar panel, a great guide is   earth4energy review .  Generating threshold is another big improvement in these newer solar panels.   The generating threshold is the minimum amount of sunlight required for the conversion to electricity to begin.   The older solar panels required quite a bit of sunlight before they would start generating power.   The result was on cloudy days or at sunrise or sunset, the panels might not produce any power at all.   Because of the reduced generating threshold of the more modern panels, they can produce power for more days of the year and for more hours each days.   This will also help people that have their solar panels mounted in a position that is less than perfect so that they can generate power for a longer time each day.   The combination of these improvements means more power produced for your home.   Making use of free energy from the sun means that will have to buy much less electricity from the power company.   If you’re interested in plans to build your own solar panel have a look at   home made energy .
