residential solar kits
Looking for wind and solar power kits that are under $ 12,000.?
My class is looking for energy engineering Wind and solar kits to the residency system in Washington State. Our budget is $ 12,000. We need a whole kit. And should generate at least 1000 watts.
A typical home needs a 2000 or 3000 Watt (2 or 3 kW) solar power unit. To power your toaster will require 1000 Watts. To power your hair dryer, it should perhaps be from 1500 to 1800 Watts. A microwave could be from 800 to 1500 Watts. If you choose a 1000 Watt system, you may have to walk around with wet hair and cold sandwiches. The price of a unit of 2 or 3 kW complete worth approximately 20,000 to $ 30,000 installed. Or about $ 10 per watt (or about $ 10,000 for 1000 watts or 1 kW). With discounts utility / Buydown / incentives, you can get the cost to $ 8 to $ 9 per watt. So you might be able to install a 1000 watt system for $ 12,000, but not sure – it could be close. The main reasons are: 1) The solar unit will work well for 6 or 8 hours a day — but when the sun goes down, your power is zero. So to make it effective, you need batteries. It would take several batteries at about $ 100 each to store energy during the day, you will be able to night. Absolutely necessary for an autonomous system if you need power at night. These batteries have an expected Life maybe 5 years or less. They will need to replace in 5 years. 2) The solar plant will provide 12 volts DC. Your home uses 120 volts to run your microwave and toaster and television. Therefore – you'll need an expensive electronic piece called an inverter. It converts 12 volt DC to 120 volts CA. This adds to your budget, and it is expensive. And it is electronic – it will fail at some point. Sometimes it lasts 5, 6 or 8 years – and needs replaced – At considerable cost. Your opinion on "wind power" are even bleaker. Similar issues as solar energy. It works when the wind blows at least 7 mph. If the wind is not strong enough, you get no power. And to think — a hot summer day is not too hot when the wind blows. But on that hot summer days — it is "very hot" because there no wind. Warm days have little or no wind blowing or they would be a "hot day". means a hot day — no fan or without A / C. The budget of $ 12,000 might install a 1 kilowatt solar unit, but it would give up a hair dryer and microwave, electric oven, dryer. Unless you're in a candlelight dinner with cold sandwiches, a more realistic solution would cost approximately $ 20,000 to $ 30,000 for a unit of 2 or 3 kW solar with battery backup.
