In this standalone system, we are building a battery that could be made with DIY materials. And it would be powered by Photovoltaic panels. There would be no need to be connected to any grid.
600KG of bio char measures roughly 1 meter cubed. The battery built would be that size or slightly larger. IT could be made of basic steel and would have to hold up to 2 ATM of pressure. The temps inside would be up to 1000c.
with a 10 kw array you could heat the battery in 10 days and then be standalone generating 30 kw hrs of capacity.
Most residential solar panels produce between 1 and 3 kilowatts (kW) of power. A solar panel’s size and the efficiency of its cells determine its power rating. For example, a standard solar panel might be rated at 200 watts, while a more efficient panel might be rated at 400 watts.
As a rough estimate, a 6-8 kW solar PV system might be sufficient to power a 2000 sq ft home and charge a 30kWh battery, especially if you have good solar irradiance and energy-efficient appliances. However, this is just a starting point, and the actual system size may vary.
COST
A 30 kw system in US dollars runs about 3$ per watt. A 30 KW system is about 60K
based on our cost breakdown of making a DIY bio char battery. The estimated cost of the battery in US dollars could be as low as 5k.
The amount of electricity a solar panel generates can vary based on several factors, including:
- Panel type: Monocrystalline, polycrystalline, and thin-film panels each have different efficiencies and performance levels.
- Angle: The angle of the solar panel can affect its output.
- Climate: The climate can affect the output of a solar panel.
- Hours of sunlight: The amount of direct sunlight a solar panel receives can affect its output.
A typical American household needs around 10,000 kilowatt-hours (kWh) per year. A 20 to 30 panel system should generate enough power to cover a typical home’s annual energy needs.
Solar installers can determine the correct panel size for a home based on the amount of electricity needed to run it.
