There is so much buzz concerning SOLAR ENERGY these days, it’s difficult to know which way to go. Could you benefit from this technology? As a Solar Energy Consultant, specializing in Commercial Photo-Voltaic and Water Heating installations, I can explain these basic facts:
– solar energy installations save you money
– solar energy installations reduce your carbon footprint
– solar energy installations PAY FOR THEMSELVES!
– solar energy installations frequently return 10-13% on investment
My direct line is 941-321-3177.
Because Solar Energy systems save you money, they pay for themselves. Since they require no fuel and have no moving parts, they are warrantied for up to 25 years. During that time they will pay for themselves many times over. That means they are a “performing asset”, just like a stock portfolio with a calculable return on investment (ROI). In Florida, at current utility rates, that ROI can be as high as 13% per year!
Hate to watch that water flow down the drain while waiting for it to get hot? Many houses utilize circulation loops that cycle the water through the pipes, keeping hot water near the faucets. Those systems require a “return loop” pipe, typically a 1/2″ line from the farthest point of use. These return lines are frequently installed in new construction.
But, what about existing homes? Now there’s an answer: the Watts Premier Hot Water Re-circulating System.
This short article describes the operation of OPEN LOOP CIRCULATION TYPE DOMESTIC WATER-HEATERS.
Your Solar Water-Heater
Your home is equipped with an “open loop solar water heating system.” This system is composed of the collector panel, a large capacity storage tank and a DC circulation pump. The pump is powered either by a photo-voltaic (PV) panel or AC power.
When the Sun is Shining…
The PV panel makes electricity that powers the pump. The pump draws the water out of the bottom of the storage tank, circulates it through the collector panels and returns it to the tank. The more direct the sunlight (striking the panels at right angles), the better the systems works.
Here in Sarasota, we attempt to orient the collector panels facing south at an angle of 27 degrees. The rule of thumb is to set the degree of tilt equal to the degree of latitude. This creates the optimum annual harvest for a fixed array.
When the Sun isn’t Shining…
The system doesn’t work. Electric elements in the storage tank will heat the water used at night or during cloudy hours. On foul weather days, the solar system may act as a pre-heater, raising the ambient temperature of the water a few degrees.
Are required on your part. When it is beneficial for water to circulate through the collectors, the pump will operate. When it isn’t, it won’t.
