If you are considering installing a home solar power system it is necessary to know what he includes: a set of solar panels, a set of solar panel mounts for fixing them, an solar inverter to match the system, a set of spare batteries, some links and installation tools, a bundle of specialized cables for the solar panels to carry the current and a bundle of cables for the solar batteries to be charged, and lastly, a solar disconnector, which is the most basic equipment for running a solar power system you can also add meters etc for ease of use.
The current price of photovoltaic panels is about $0.1/watt, the price of lithium batteries is about: $130/kwh, photovoltaic mounting for photovoltaic panels 1/4 of the price of the average household monthly use of electricity in the 1100kwh or so so installing 10kw solar panels is the best, on the average household to install a 10kw solar panels, for example:
First of all, 10kw solar panels are divided into 18 power 550w individual solar panels according to the price of $72 each solar panels cost a total of $1296, solar racking for the photovoltaic panels of about 1/4 of the $360, the choice of inverter is the specifications for the installation of solar energy systems ordered a 10kw solar inverter for $950 or so, the battery pack costs the most but is inevitable for nighttime use. But for the night use is unavoidable, a set of 20kwh battery pack for about 2500 U.S. dollars, a bundle of 200 meters of solar cable for 200 U.S. dollars, connecting and assembling the solar cable tools for 20 U.S. dollars, battery cable and solar disconnect for 180 U.S. dollars, summing up the basic cost of home solar energy system for about 5500 U.S. dollars.
(1) labor costs, the installation of home solar panels for the majority of users to choose the installer, whether the seller to provide services or third-party installation companies need to calculate the cost of labor installation costs separately, but the cost of labor in various places according to the economic level of each place there will be substantial changes in the price can not be determined, according to the United States the cost in the range of 50 cents to $ 1 per watt.
(2) home solar energy legal rights license, the use of home solar panels need to be inspected to provide a license, for compliance and installation of safe home solar energy system in order to enjoy the state subsidies and grid-connected electricity sales, need a few hundred dollars, according to the price of each region is different for some regions have set a fee for the standard residential is generally about $ 500.
(1) government incentive programs, for the installation of home solar panels for the use of solar panels will receive a check before the use of solar panels to obtain a permit, and then you can apply for reimbursement of fees from the government can reach 30% of the cost of purchasing solar energy, to facilitate you to reduce costs.
(2) home solar system size, generally the larger the system size the more expensive home solar panels, we have selected some real cases of home solar system, for example:
3kw home solar system $1700
5kw home solar system $2700
10kw home solar system $5,400
15kw home solar system $7,600
20kw home solar system US$11000
30kw home solar energy system $17000
(3) family house environment, the complexity of the environment around the house will increase the cost of manual installation, for roof installers to carry out additional processing to ensure the comfort of the house at the same time as solar fixed tilt angle processing, if there are a large number of trees around the need to cut down the wood blocking these treatments in the 300 to 1500 U.S. dollars ranging.
(4) maintenance costs, although the solar energy to provide quality maintenance guarantee but limited to direct replacement of damaged products, for must come to the door to repair but not need to replace the case to pay a separate maintenance costs.
For the average user of the solar energy system is about 10kw, the cost of equipment costs plus labor costs plus inspection costs, and finally government incentive programs to reduce the cost of about $5,000 to $6,000, this cost is about 5 years to get a return, he will bring a substantial savings in the home electricity bill.
