The books still out on this one. On one hand, it’s the most expensive form of renewable energy we have. On the other hand, it’s also technically the most renewable, emission-free resource in the world.
Yes it is. Solar energy might take a lot to produce the solar panels now but the technology is getting better and production getting cheaper. Solar power, in the right place can make houses zero energy and actually put energy back onto the grid.
Thanks to a drop in production costs and federal and state tax incentives – both solar electricy and solar thermal are becoming more affordable. Solar Thermal is the cheapest form of solar technology – a typical residential system is about 1/3 the cost of Solar Electricity and takes up 1/5 of the square footage. Depending on energy costs, payback time for solar thermal is usually 6 to 10 years and electricity around 10-15 years.
