Solar load calculator.
List your appliances, estimate daily energy use, and send the results to Darbot on WhatsApp for a sized quote.
One of the most important things to do BEFORE going solar is to calculate the amount of electricity you are currently using. You will use this information to determine the size of solar power system you will need. Our Solar Load Calculator can help you calculate your system load.
NOTE: This calculator is intended for helping us determine your energy requirement for small systems less than 5kwhr. For big and commercial systems, a physical assessment is required to carry out proper energy audit. Please contact us directly for consultation.
How to use
- Add each appliance you want on solar backup.
- Enter Hrs/day for daytime use and Hrs/night for evening and overnight use on battery.
- Unsure of wattage? Use Add from load chart for common items.
- Review your daily totals, then send the summary to Darbot on WhatsApp for sizing.
Estimates for off-grid / backup sizing. Hybrid or grid-tie systems may also need your NEPA bill — our team will confirm.
