Q. What are engineering challenges to develop solar energy for comfort/home uses?

A. Solar is an old technology now and is fairly developed. Cost is a bit of a barrier but that is coming down quickly. Production scale could also be considered a barrier, as the industry can't yet make enough solar panels to satisfy demand. The panels themselves are limited in how much energy they can take out of the sun's rays, but they are getting better at this. Materials are a big thing now, mostly in trying out different materials and structures in the cells to bring down the cost and boost the efficiency.

Q. How the electricity is produced by using solar energy?

Q. Please describe in details how do the whole mechanisms work? How it is developed? What apparatus is required? How the solar panel is constructed and how it works? Explain me all questions by using 3d figures or images or video if available. I have no prior knowledge about solar electricity so; please guide me in the easiest way as much as possible; I want to make electricity for my home by using solar energy what should I do? How can I achieve or construct it myself?

Can you give me information on solar energy?

Q. I would love to use some solar energy in my home. What can you tell me about how much it costs to begin? Is there some sort of federal tax credit? What all do I need to buy (panels, batteries, etc)? Can a homeowner do the installation or must it be done by a professional? Would also appreciate any websites for retailers of solar energy items. Thank you very much for any information.

A. When I was gainfully employed, prior to experiencing the bliss of retirement, I worked for a hardware store that marketed a solar energy system for single family residences.

The cost profile (this stuff is expensive) suggested that, if you planned to live in your home for 19 years post-installation, you would amortize the cost.

There were federal and California state tax credits available at the time, as well as a rebate from Pacific Gas and Electric (primary utility provider in No. Calif.) which produced a net cost near $20K.

You need to determine if your local power company is obligated to buy back surplus power from your solar system first. If they are not legally required to do so, that will make amortization more difficult.
