solar electricity and hot water
When considering solar hot water (DHW) systems, also worth looking at water use in the home. While saving money in a solar hot water system, it seems unreasonable to continue to waste a valuable resource. supplied water to keep your house has power to store and pump to your door, whether a deposit is water or soil. So rather than choosing a storage or the heater unit in size, take a look at their real needs. However, the fact is that ACS unit can probably get most if not all their needs, although in size and established. Even a snowy climates benefit from solar units hot water. When you combine a solar hot water with solar energy, you can make big savings in energy consumption. The great thing is, if they are useful, DIY projects solar hot water or solar energy, are quite viable.
If you consider the number people at home, we can work back to the volumes of typical use and hence the size of the storage unit and the area of solar collectors.
A storage tank of 200 liters (50 to 60 gallons) is about right for a maximum of three people when used with some awareness of their use. Larger systems 300 liters (80 gallons) suite of three fifty-seven people. With larger families, have more storage or possible some sort of "booster" to compensate for nay "solar energy deficit. Depending on what you set your systems temperature and the temperature of incoming water, the system will have reflect the size of the collector. If you live in climates with snow, cold water has more heat and there will be heat loss unless the unit is properly isolated.
What does this mean in terms of size collector? Typically, for about 2 square meters per person up to 2 people, and after you add a square meter for each person. This enables the seasonal variation of hours of sun and solar heating. Lets face it, with a little more of the solar hot water capacity is always welcome, especially when the heat is free. The added cost of adding additional collection unit little to the overall installation. If you live in snowy climates or areas with lower sun intensity or hours as the bottom of the north or south latitude, then always err on the larger size of the collector.
