When the sun strikes your roof, it heats the water and air which then creates electricity. The energy is used to run lights, air conditioning, fans and pumps to keep warm, as well a large generator that is used to heat water near your house. Most small-scale renewable energy is run off your rooftop solar panels and not a utility’s grid.
How much of the water does a solar water heater use in New York?
At any one time more than 50% of the water used by the solar water heater is used for power and heat, and another 25-30% for the water heaters, said the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), a trade group. With an average of 300 gallons per day or 2.8 gallons/hr per month, a solar water heater needs to be able to use approximately 1.3 gallons of water per day to supply an average water heater. To power your water heater, you must charge one of your solar panels that will supply 3.3 kilowatt hours (kWh) or more using 24 kilowatt-hours (kWh) or more in use.
How much does a solar water heater cost? What is the annual income for my family?
Solar water heaters have an average cost of $9,000 and a cost of energy (CO) to produce a kilowatt-hour (kWh) of energy to heat a home for a typical family of 4 is approximately $0.22. To generate 3.3 kWh, you must buy the electricity from the grid. In comparison, your monthly bill (a fixed electric bill) for a standard home will be between $350 and $500. If you have the solar water heater to supplement your grid power, you can save money. For example, you can buy one kilowatt-hour (kWh) of power and the equivalent of $6 per month for a solar water heater. For the typical New York family, a solar water heating system would cost around $30,000. Even the cheapest water heater will provide a substantial benefit.
How do I determine if my city’s solar energy is suitable?
In cities with a large number of solar panels installed, it is best to use a site surveyor to figure out which panels are the best fit, since they are the simplest and most obvious choice. However, the best place to place a solar panel is on a street
