Solar cell performance hasn’t been all that remarkable before recently. Multicrystalline panels will be one case. We vary in performance from 12 per cent to 17 per cent. The bulk of home solar panels are installed this way. Checkout Barrett Solar Near Me.
And we have solar thin film or transparent panels. Such efficiencies will vary from 5 percent to-8 percent. They are the panels you see that will hold the battery powered on your vehicle or ships.
“Spray on solar” is the latest in alternative energy technology You can experience what is known as Quantum Dots Solar Electricity. A basic reason for quantum dots is their being a semiconductor. These may be rubbed on to a range of fabrics when mixed with a specific solvent.
So here’s the surprise. Solar cell efficiency was low until these dots were discovered, because the panels could only absorb visible light. That’s why they couldn’t create solar panels at night. Quantum Dots is a composite that reacts both to visible light and to infrarot light.
The idea is that because infrared light appears both during daytime and night the cycle of insulation is extended and the quality is increased. We send off heat from infrarot. Something heating up will send off heat from the infrarots.
You may thread this renewable energy technology into clothes and use it to run a mobile phone or even a laptop. Imagine your phone plugging into your top. Any of the big Solar Companies who do their own development there are researching the possible applications.
They expect the output of solar panels will hit 30 percent by 2011. The real structure will be integrated into many forms of roofing structures, because it is modular. We still have Solar Shingles and they’ll be able to do an much greater job with this new invention.
One of the major pitfalls Solar faces is the expense. The cost keeps falling, but you’re always looking at $8-$10 per watt somewhere. Installed a 3KW (3,000 watt) system runs $24,000-$30,000. The excitement about Quantum Dot Solar Power is that the cost could collapse from $1-$2 per watt down to a fraction.
When contemplating solar or something else for that matter, most people look at the payback time. This depends on the energy costs per KWH so I recommend that you look at the rate of return. The cost is falling as I said.
Ask your contractor for an estimation of what the solar saves you per month. Then (in the United States) subtract the overall expense by 70%. It would be the total expense until the tax deduction of 30 percent if you have no other State benefits.
