Residential Solar Energy Storage System
How could I build 20KWH capacity solar energy storage system?
SolarDyna brand 20kWH storage is sufficient to support normal residential home appliance using. No mater
the sudden power off in electricity unstable regions, this storage could support enough electricity for residential electrical devices normal operation using such as fridge, lighting, office devices, etc.
Solar energy storage connected in the solar power system, it could effects of solar energy stored via DC charging. In our normal houses, depending on the ground or roof space, normally people could mount PV panels on the rooftop like as 6KW- 10KW or larger. 20KWH storage batteries could save the electricity from self solar panel energy generating.
Specially in the night, using electricity from the solar energy storage battery system could take full using of the solar power to reduce the electricity consuming from government.
In a word, solar energy storage system is the one of the best option from investment, durable using, and environmentally friendly speaking.
How to see and count the the solar power generation efficiency?
Taking a region where day time duration of sunshine is 4.5 hours per day for example.
The solar system efficiency is 85%, how could we know the power capacity of solar panels we needed to support the 20KWH storage system?
Solar panel power capacity (kW) = Daily electricity generation (kWh) ÷ Daily sunshine hours (H) ÷ System efficiency
20÷4.5÷85%≈5.2kW
By taking the certain margin into account, we could count that the 6KW capacity solar panel is sufficient.
However, this is a rough estimate for reference only. The actual configuration counting should consider of real site circumstances.
The places like as islands, unit cost of electricity bill is high, or power system not stable.
Then how to select the right battery model for the 20kWh solar storage system?
- One integrated housing design. You could benefit from simple using without complex cable connecting, terminal connecting, etc. And the design with wheels could be easily moved.
- We also recommend you choosing the stacked model design by series connecting with 4 units of 5kWh Lithium battery, this is easily stacked with special cable connecting in series.
SolarDyna has full series of necessary certificates such as CE/MSDS/UN38.3. We are offering 5 years warranty to make your using safely.
