Frequently Asked Questions — Solar Panels
Sizing, cloudy-day performance, connections and warranty.
What size solar panel do I need?
Start from your daily energy use in kWh. In Kenya a panel produces roughly its rated watts x 5 peak sun hours x 0.8 per day — so a 200W panel gives ~0.8 kWh/day and a 400W panel ~1.6 kWh/day. Divide your daily kWh by that figure, then add 20% for cable and inverter losses.
Will it work on cloudy days?
Yes, at reduced output. Heavy cloud can cut output to a small fraction of the rating; light cloud cuts it far less. Size the array and battery bank with 30-40% margin if you need dependable power through cloudy spells.
Monocrystalline or polycrystalline — which is better?
Monocrystalline panels are more efficient (18-23%) and use limited roof space better. Polycrystalline is slightly less efficient and cheaper. Check the cell type in the specifications above.
What do I need besides the panel?
For a battery system you need: a charge controller (MPPT preferred), a battery, and for AC appliances an inverter. Solar cable and DC breakers complete the set.
