Will the same amount of solar heat be transmitted through a non-clear object, as a clear object? thanks
Less heat will go through non clear objects.
Two possible explanations: Simple and complicated.
1. Heat is transmitted by infra red light. Infra red can be attenuated (made less) by passing through objects. The less...

Solar Energy works by converting sunlight in electricity. It produces Direct Current (DC) which then has to go through an Inverter which converts it into Alternating current (AC) which then ties into your power box.

I don't really have a clear idea of what development of solar energy technology would be like. for ex. If that would require research etc.
Engineering of some form, probably electrical.

The intensity of electromagnetic waves from the sun is 1.4 kW/m^2 just above the earth's atmosphere. Eighty percent of this reaches the surface at noon on a clear summer day. 80% of 1.4 = 1.12 kW / m²
Suppose you model your back as a 27cm & 51cm rectangle.
Area = 0.27 * 0.51 = 0.138 m²
Power = 1.12 * 0.138 = 0.154 kW
Energy = Power * Time
Time = 0.7 * 3600 = 2520 seconds
Energy = 0.154 * 2520 = 389 Joules
how many solar energy needed to clear up one ton of CO2?
In general, a coal burning power plant produces about 2.3 lbs CO2 per kilowatt-hour (kWh) of electricity. An English ton is 2000 lbs. Therefor, 1 ton of CO2 produces about:
(2000 lbs) / (2.3 lbs / kWh) = 870 kWh

Isn't it a little flawed? What about the places in the world that barely have clear skies and it's always cloudy? I like the idea because it can help us, but to what extent?
Yes indeed, we have quite a way to go

UK Solar Capacity Surge Defies Huhne's Plan to Curb Subsidy
Jan. 12 (Bloomberg) -- Britain's solar capacity shot up 10-fold last year, defying Energy Secretary Chris Huhne's effort to roll back subsidies for the industry and prevent the sort of booms experienced in Germany and Italy.
Solar panels with at least 761.9 megawatts in capacity were installed in 2011 compared with 76.8 megawatts the prior year, according to figures on the website of U.K.'s energy regulator Ofgem. About two-thirds of the capacity and 95 percent of the projects were installed on homes.
Huhne twice last year moved to rein in support granted in April 2010 in the form of feed-in tariffs, which guarantee premium rates for electricity from solar power. Companies including EON AG, Tesco Plc and Carillion Plc's Eaga rushed to tap the market, supported by fund managers such as Foresight Group LLP and Octopus Investments Ltd.

They scavenged 20-30 car batteries and hooked them together. The weaker ofthe batteries will bring down the others. Just don’t drain the batteries too much under 12V. Batteries I’ve learned like to be kept healthy if always charge. Run everything you can when the sun is shining. Use those batteries as a buffer. Always keep a volt meter on them.
It has been clear and sunny all day, after Iread your post i ran my 500w leaf blower on the powerbright. The cable to the positive side on the terminal was getting really hot to the touch. So…..mabe if too much current was flowing it could melt the casing…? The batteries are sealed Absorbed glass mat (AGM) They are notsupposed to vent hydrogen gas with normal use....News
