Question by Psssst! wanna send a letter?: What’s the difference between a proper Solar water heating panels?
and household radiators painted black and housed in a cloche. Being a tight git I built my Solar water heating system for £180. It’s three 1.2m x .6m panels, a pump and a controller. It gives me tons of hot water on a sunny day and does a bit even when it’s not sunny. So whats the difference? Why do people spend £7000 on solar water heating systems?

Question by jay: The Sanchez household is about to install solar panels to reduce the cost of heating their house. ?
In order to know how much the solar panels help, they record their consumption of natural gas before the panels are installed. Gas consumption is higher in cold weather, so the relationship between outside temperature and gas consumption is important. Here are data for 12 consecutive months:
Degree days193300081127463834
Gas used3221.610.70.71.63.15.17.776.1

Question by TxVarmit: How many solar panels does it take to run an A/C unit? Also, How many batteries in an array?
I was wondering how many 700 W solar panels it would take to run a household A/C unit. Also curious how many batteries it would take to keep A/C running in inhospitable environments. Would a 3500 W inverter be enough if it were to run 220 AC?

Question by Charlotte: Where can I buy solar panels to make a solar powered cell phone charger?
Back in high school it was going to be a school project for our science team but the plan never worked out. Two years later I am finally going to do it. I live in the Asbury Park, New Jersey area. Is there a store that is located a decent distance to buy them? Is there a reliable online source?

Question by TC: How do solar panels and solar energy connect?
Does the solar energy hit the solar panels and creates electricity.. or what ?
Where can you put solar panels ?
Best answer:
Answer by spikesolar panels take the energy from the sun’s light which is more intense than say a light bulb and using the chemical properties of (i believe it is a silicon and carbon based material) the material to transform the light(but not heat) into electrical energy. It can only use very specific wavelengths which is why solar cells are nowhere near efficient. oo i forgot [...]
