SAVE ENERGY
Wyse solar solutions were contracted to analyze the client's energy usage and make proposals regarding the installation of P.V.
The proposal suggested the installation of a 2.4-kWp array in conjunction with an optimizer to divert the excess power generated and not used by the house by the array to the electric elements in the existing immersion tank.
After monitoring the system for four months the results confirmed that the system achieved its objectives. The house (4000 square feet has a running cost of €9.00 per seven day week more than halving the original cost with the added benefit of hot water.
The graph below (Ashford Co. Wicklow 31-05-07) contains the data we recorded on 31st May 2007. This is a "single-frame" picture of the performance of the system on a typical sunny early summer day (the met office recorded 11.3 hours of sunshine at Dublin Airport on 31st May 2007). It shows that the total amount of electricity drawn from the grid was c.7.7kWh - most of which was consumed at night. It also shows that the arrays started generating power shortly after sunrise (you can see the load dropping immediately) and continued to do so until around sunset. The array output met or exceeded the household load (including hot water) from 9.00 am to shortly after 3.00 pm apart from a short period about 1.15 pm.
