Electric solar panel myths Solar panel myths are questions we have heard of being asked about solar panels. First solar panel FACTS: Solar panels will only produce a useful amount of electricity under bright sunlight, if its over cast they will not provide 100% of their output. Most solar panels are 12v DC. Your household runs on 230v AC (This is U.K. site) A solar panel output is measured in Watts. Now the Myths. Can i run a fridge with no battery? No, but if you could how would the fridge stay cold at night? (no sun at night)
Does the panel need to be under the sun all day to charge? (a battery) Why do you suppose it is called a Solar Panel
Will a 10 Watt panel power my portable TV (Back of my tv says 12v 50W) If the TV is 50 watts how do expect to make it work with only 10W
Can a 43 W panel be used to power my home? Your home uses 230v, solar panels are only 12v, the smallest lamp is probably 60 w, how do you suppose a 12v 43 watt panel will run your house?
Can I use a solar panel to heat water? That is a water solar panel, these myths are about electric solar panels.
I have seen it on tv, they put electric solar panels on the roof they run the whole house, is it true? Depends on how big the house is and how efficient the solar panels are, and also not forgetting how deep are your pockets. (That is one thing they often don't mention, the actual cost of the solar panels) Often they fail to mention that solar panels don't work in the rain, snow, overcast days, night etc
Can a solar panel power a regular 40 watt bulb ? No. Solar panels are 12v 1-2 w, some are 30 Watt, how can you light a 40w light bulb with only 30watts? Not to mention solar panels only produce 12-14(ish) Volts, a mains lamp is 240 volts
Can an 80 W panel run a room heater ? Electric heaters are around 2-3 kw how can you get 3,000 watts from an 80 watt panel?
Can a solar panel supply power for my outside swimming pool heater and pump As with room heaters, pool heaters are in the Kw range and a pool pump will be around 500w.
Would an 80 w panel run a pc, a light and a heater, its for a building site cabin No. All the above questions are genuine, the answers are true, but more "colourful" and if you think about them, the answers are obvious. If you have a comment, send it in. |
