Solar panels are generally sold per watt. When it gets five hours of sun direct, a 300 watt panel generates 547.5 kilowatts worth of electricity. However, solar power will not be as efficient in winter.
The cost of solar panel installation will vary depending on the location, climate, number of bedrooms, and other factors. For example, the east coast is less exposed to sunlight than the west. The midwest also receives five hours more sunlight per day than the six hours that the west coast receives. Additionally, solar panels must be installed on second-story roofs. This will make it more expensive than a flat roof.
Depending on how large your solar panel system is, you could save as much as $30,000 over its lifetime. A variety of tax incentives and credits can also reduce the cost of solar panels. These incentives are available in many states. Tax credits are worth 26% to 22% of a solar system's cost. Solar panel systems are eligible for tax credits from the state and local governments in addition to federal tax credits.
Solar panels cost will vary depending on how large the system is and what equipment it uses. The cost of solar panels for a 2,000 square foot house will range from $18,500 to $42,000. The cost of solar panels for a 3,500 square foot house will range from $19,000 to $32,000.
The size of the solar panel system you want will be determined by the amount of sunlight your area receives. Standard solar panels do not produce as much electricity as the best solar panels. The panels can be purchased cash or financed. Solar panels typically come with a warranty of 25-30 years.
The cost per watt of commercial solar will be lower due to the economies of scale. The cost of a commercial system with solar panels will include the installation, solar contractor fees, as well as solar modules. The cost per watt will vary depending on the size and configuration of your commercial solar system.
For commercial solar systems, there are tax incentives. These include the Class 43.2 Accelerated Cost Allowance which can offer a higher rate return. Commercial customers may be eligible to receive tax credits in addition to community solar programs. Numerous energy companies also offer local rebates on renewable energy equipment. Commercial solar's cost will depend on the size, type and location of the system.
A 5,000-watt solar panel, for example, will cost anywhere from $5,600 to $6,000. This cost will include the solar panels, the inverter, and other parts. Ceramic tile roofs or slate roofs will have higher installation costs. Installation of 20 kilowatts solar panels will cost you between $15,170-$24,500.
