Hello, We had extensive problems with the bog, but I’m now hoping we’re back on line. Let us begin.

Solar tax credits

Can you tell the latest on the Federal and
State tax credits for solar and/or energy
installation products? Thanks

Photovoltaic panels

January 19th, 2010

I read that the price of phtovoltaics panels
has been reduced because of more
manufacturing capabilities. What has happened
to the panel costs?

What’s the best insulation to use in new construction?

Winter plumbing

What are the issues and items I can do to save energy, and money, on my water system in my house? Do pipe wraps and hot water heater “blankets” really make a difference?

Evacuated Hot Water Tubes

September 13th, 2009

I understand that evacuated hot water solar tubes are “more” efficient than other flat panel systems.  They seem fragile and vulnerable to breakage and are they really worth the extra cost?

Solar

August 31st, 2009

Planning on putting a solar panel on the roof of our boat house to charge batteries for an electric engine. It is a 24 volt system. Are 4 six volts batteries better than 2 twelve volt batteries?

If I wanted to boost the 24 volt reserve could I use double the batteries?

What is the configuration of serial vs parallel?

Solar panel ratings

August 1st, 2009

If a solar panel is rated at 190W, what does that mean? I have a product bulletin that rates a panel @ 190W with an efficiency of 12.7%. Can this panel produce 190W and what is the time span used to produce this wattage.  190W an hour, or month, or year?

I understand average sunlight hours etc., but coming up with reliable numbers based on wattage is escaping me.

Thanks

Solar hot water

Can you tie a new solar hotwater system into your existing water system?  Can I use my existing hot water tank as the storage for the solar hot water I create?
