Home solar power is a great option for clean, renewable energy. Whether on or off the grid, home solar energy systems come with a number of benefits, including federal and state tax credits. As the home solar energy industry expands, the number and types of jobs performed by solar contractors in Contra Costa County expands as well. They can install all of the necessary components for a new residential photovoltaic system, solar water heating, solar pool heating, and more. These home solar contractors can guide you through the solar system design process to arrive at the optimal solar electrical or solar thermal system for your home solar energy requirements.
Solar Water Heating is Different From Solar Power
Some solar contractors may do only solar water heating or only solar electricity, or both. What's the difference? Solar hot water systems are to generate hot water for your home only, and not to generate electricity for other appliances. Solar water heating systems include storage tanks and collectors.
Most solar water heaters require a well-insulated storage tank. In two-tank systems, the solar water heater preheats water before it enters the conventional water heater. In one-tank systems, the back-up heater is combined with the solar storage in one tank.
There are two types of solar water heating systems: ACTIVE, which have circulating pumps and controls, and less-expensive PASSIVE, which don't.
Types of ACTIVE Solar Water Heating Systems
Direct Circulation Systems: Pumps circulate household water through the collectors and into the home. They work well in climates where it rarely freezes.
Indirect Circulation Systems: Pumps circulate a non-freezing, heat-transfer fluid through the collectors and a heat exchanger. This heats the water that then flows into the home. They are popular in climates prone to freezing temperatures.
Types of PASSIVE Solar Water Heating Systems
Passive solar water heating systems are typically less expensive than active systems, but they're usually not as efficient. However, passive systems can be more reliable and may last longer. There are two types.
Integral collector-storage passive systems: These work best in areas where temperatures rarely fall below freezing. They also work well in households with significant daytime and evening hot-water needs.
Thermosyphon systems: Water flows through the system when warm water rises as cooler water sinks. The collector must be installed below the storage tank so that warm water will rise into the tank. These systems are reliable, but contractors must pay careful attention to the roof design because of the heavy storage tank. They are usually more expensive than integral collector-storage passive systems.
SOLAR COLLECTORS FOR SOLAR WATER HEATING
For residential solar water heating systems, there are three types of solar collectors:
Flat-plate collector: Glazed flat-plate collectors are insulated, weatherproofed boxes that contain a dark absorber plate under one or more glass or plastic (polymer) covers. Unglazed flat-plate collectors-typically used for solar pool heating-have a dark absorber plate, made of metal or polymer, without a cover or enclosure.
Integral collector-storage systems: Also known as ICS or batch systems, they feature one or more black tanks or tubes in an insulated, glazed box. Cold water first passes through the solar collector, which preheats the water. The water then continues on to the conventional backup water heater, providing a reliable source of hot water. They should be installed only in mild-freeze climates because the outdoor pipes could freeze in severe, cold weather.
Evacuated-tube solar collectors These use parallel rows of transparent glass tubes. Each tube contains a glass outer tube and metal absorber tube attached to a fin. The fin's coating absorbs solar energy but inhibits radiative heat loss. These collectors are used more frequently for commercial solar applications.
Solar Power Systems (Solar Electricity)
Solar electric systems, also known as photovoltaic (PV) systems, convert sunlight into electricity for your home. PV solar panels can be mounted at a fixed angle facing south, or they can be mounted on a tracking device that follows the sun, allowing them to capture the most sunlight over the course of a day.
Because of their modularity, PV systems can be designed to meet any electrical requirement, no matter how large or how small. You also can connect them to an electric distribution system (grid-connected), or they can stand alone (off-grid).
