Solar panel Efficiency in Tropics?
The equivalent full sun hours in the tropics is around 5h a day, though the sun is around for 0 or more hours. This is to do with angles of a fixed panel. If the panel tracks the sun, it would be a bit longer, maybe 8 hours. The panel is rated for 000W in equivalent full sunlight at 25°C. As the panel temperature increases to 50 or 60°C, de-rate to 800W, and multiply that by 5h = 4kWh. This varies over the year. This is the energy the panel is capable of providing, which depends on just what it is connected to. Generally an MPPT controller (maximum power point tracking) will get the best result. If charging a battery, the energy is less, because of charging losses. This is a rubbery figure because the battery may not be a simple charge/discharge cycle, but allow about 75% of the 4kWh above. Any shading on part of the panel can reduce or stop production, or cause damage to the panel even. This is what the brown marks sometimes seen on some cells in a panel are usually caused by.
Solar cell has efficiency from 0% to 5% max. That is the technology we have as for now. It stated 000W, that means it could provide 000W under fully super condition . KWH is not a unit to rate solar panel, it was used for wattmeter that company installed in every house to monitor electricity usage.
Duh - 000 W panel (rated in good sunlight) in 0 hours of good sunlight. Let me see - 0 * 000 = 0,000 wh or 0 kwh. Yup.
