If you cannot afford a full-scale solar energy system, consider investing in a smaller one. Some vendors offer small systems designed to power a water heater or a generator. This small investment should help you save money within the next few years and you can easily expand your solar energy system by powering more appliances with solar panels.
Check that your solar-energy installer has the proper licenses and insurance. Installing solar panels on a steep roof is a delicate job, and you should feel confident that your installers know what they are doing. At a minimum, look for a contracting license, workers compensation insurance, and general liability insurance.
Just a quick video showing a 1st generation prototype for building thermal heating panels from recycled materials. not to shabby for under $150 bucks! Thanks …
The amount of electricity you generate from solar panels is dependent on how many panels you install and the efficiency of these panels. You will need to do a little math to calculate the number of panels you will need. Higher-efficiency panels are often your best bet cost-wise.
