Wow, isn’t Solar Power really unimpressive ?
Hi Folks,
I am all for natural energy, so fitted a few solar panels to the boat roof.
So there are 576 little bi-silicon discs doing their utmust on a bright sunny day.
I can power up a little calculator, a 2 inch plastic fan, one LED, and a plastic bobbin with light thread on that can just about lift up a sheet of toilet roll.
It is pathetic.
I have calculated that I would need to cover the whole 60ft X 7ft roof, and given maximum sunbeams, it might put a decent light on, but then, I wouldn’t be needing the light I suppose.
These things are not cheap, either.
Any notions ?

Well, it sounds like you have not set the solar cells up properly. The sun creates a tremendous amount of power that is incident on the earth, about 1000 Watts per square meter. A reasonable solar cell should be able to convert about 10% of that into power, giving you about 100 W/m^2 or a 10cm by 10cm cell should give you 1 W (that only counts the active area of the cell). By contrast, a 9V battery, run in a way that would drain it in 4 hours would provide about the same power (1 W). Of course, no one uses up a battery that quickly, so a more realistic power from a battery is about 0.05 W. That means the 100 cm^2 solar cell should be able to power quite a bit more than a 9V battery. Therefore, it really sounds like you may have hooked up your system wrong.
The voltage that you get out of a solar cell is pretty small. If you wired them up in parallel, your output voltage would be small as well. And if you hooked them up in series, your output current might not be big enough. And if you hooked them up reversed… well… then it wouldn’t work very well at all. I don’t know how you hooked them up or how much surface area you have, or how you are trying to apply the electricity to your devices, or even how much you know about all this. But if you can’t run a calculator on something that is bigger than the typical solar cell on a hand-held calculator, it sounds like you must have done something wrong. And given that you are trying to run a fan (often times these are AC devices that need 120 V), a LED (these are DC devices that need very little voltage but MUST be setup in the correct circuit and receive the correct current and voltage), and a calculator (these often run on batteries with out any external connections), it sounds like you may not realize what each device needs or What You are giving it.
Solar Hot Water
Solar Hot Water is the H2O heated using energy from sun that is Solar Energy. As you may have noticed that the shallow water of a lake is warmer than the deep water because the sunlight directly heats the lake bottom in the shallow areas. In the same way, sun can also be used to heat water in buildings and swimming pools. The solar heating systems is generally used to heat water for home, business and industrial usage. Hot water heated using sun’s energy helps in generating electricity and can be used for sanitary purposes such as showering and washing.
Solar hot water systems are storage systems that can provide up to 90% of your hot water for free. In smaller households or in cooler parts of the country solar systems may be less appropriate depending upon climatic conditions. Solar heating systems is composed of solar thermal collectors and a fluid system to move the heat from the collector. The system have tank for heat storage. Solar hot water systems use flat-plate solar collectors that are typically installed facing in south direction on a rooftop. The collectors are made up of simple glass topped insulated box containing a flat sheet metal solar absorber attached to copper pipes and painted black. To heat water using sun’s energy, a collector is secured on wall facing the sun. The most common solar water heating systems are active systems. Active systems contain pumps to move the liquid between the collector and storage tank whereas, passive systems rely on gravity.
Rheem is one of the leading US manufacturer of solar storage tanks. It is basically used in residential solar water heating applications. Solahart is also a Rheem company since 2002, manufacturing solar water heating systems and collectors for over 50 years and most trusted in United States.
