solar panel energy storage
Gas and electric hot water systems account for approximately 20% of emissions of greenhouse gases a home, and by installing a solar water system you can reduce these emissions and also save up to 75% of your water heating costs! Table below is derived from the Debartment Environment and Climate Change NSW.
There are two types of collectors:
- flat plate collectors (great for when the tank should also be mounted on the roof)
- vacuum tubes (ideal for areas prone to frost)
Flat plate collectors work on copper pipes running through a glass covered collector, often connected to a water storage tank on the roof. Water can thermo-siphon hot in and out of the tank, thereby heating the water. The upgrade option of flat plate collectors are vacuum tubes.
Tubes vacuum using a glass tube with a vacuum inside it and copper pipes running through the center. Copper pipes are all connected to a common manifold which is then connected to a slow flow circulation pump which pumps water to a storage tank below, thus heating the hot water during the day. Hot water can be used at night or the next day due to the isolation of the tank.
The evacuation tube system are superior as it can draw heat from the air on a wet day and does not need direct sunlight. Because of the vacuum inside the glass tube, the total efficiency in all areas is higher.
Heating solar pool uses technology similar to building / household solar hot water systems. Solar pool heating involves covering a roof with a black mantle of the coils and pipes that are also heated by the sun, combined with a slow flow of the pump that circulates water through the panel and in the pool. Unfortunately Energy Matters only installs building / household solar the water heating systems and does not perform the installation of heating the pool water.
