If the solar module is 2000 W: the whole system will cost: approximately 38,000 yuan
Calculation if the load is 2000 W: or 2 kilowatt hours of electricity per day:< /p>
A 700 W module is enough. Yes, 4 50Ah batteries plus inverter wires and other accessories cost less than 10,000 yuan.
Problem of solar water heater accessories
Production domestic solar energy is not cost-effective. . Installing a solar power generation system requires a certain initial investment cost, including the costs of purchasing and installing solar panels and the costs of purchasing associated accessories. The cost of solar panels constitutes the major part, along with the prices of solar panels of different brands and. the models are also different. The market In the market, the price of some well-known brands of monocrystalline silicon solar panels ranges from 1.5 to 2 yuan per watt, whilethat some high-efficiency and expensive solar panels exceed 2 yuan per watt. The operating cost of a solar power generation system mainly includes maintenance costs and labor costs. Cleaning and maintenance of solar panels needs to be done regularly and the cost is relatively low and borne by the family itself.
A set of fully automatic instruments (including solenoid valves, thermal sensors, instruments)
Electric heating (installed on the solar host before leaving the factory)
Leakage protection cap, automatically cuts off the power within 0.1 seconds if a leak is detected)
Check valve to prevent hot water from flowing back
Shielding wire, PEX pipe, insulation pipe, anti-adhesive tape, aluminum foil, copper accessories, etc.
I am the agent by Wuxi Huangming Solar. These materials arenot included in the installation. The price of a solar installation for a family of three is between 2,000 and 3,000 wait.
