Solar Power Battery System Cost

If you re going solar with a grid tied solar system it s worth considering battery backup as well.

Solar power battery system cost.

For example the tesla powerwall 2 with 13 2kwh of storage capacity will cost around 14 000 fully installed while the 9 8kwh lg chem resu h battery is closer to 9000 plus the extra cost of a compatible hybrid inverter and installation. The life of the battery storage system will vary depending on a number of factors including but not limited to. Solar batteries range from 5 000 to 7 000 and from 400 dollars per kilowatt hour kwh to 750 kwh. As a general guide a battery system will cost between 800 to 1200 per kwh installed.

Small solar batteries run between 200 and 2 000. The average solar panel payback period is 7 to 12 years and solar energy saves 600 to 2 000 per year on electricity costs. The battery storage system should not be relied upon as a power source for critical medical devices. The battery costs between 6 500 and 8 000 as an add on to a new sunrun solar system depending on whether you purchase or lease your solar system.

Note that these prices are only for the battery itself not for the cost of installation or additional necessary equipment. But as a starting point the price of solar battery storage starts at 5000 or around 105 a month over 5 years for a smaller enphase system while larger batteries such as tesla powerwallstart at around 12 500 14 000 depending on a number of factors. Solar battery faq how much do solar batteries cost. Grid tied systems are often the easiest and most cost efficient type of solar system to install.

The amount of energy stored in the battery the amount of wattage used by the appliances and electronics connected to the battery. That averages out to around 660 800 per kwh. The installed cost of a battery is closer to 11 000 to 18 000 and 800 kwh to 1 300 kwh. However a quality battery for residential solar energy storage can cost up to 7 000 or more.
