Intelligent Management of Solar PV
15 March 2012, News release from Greenologic Ltd
So you've installed a Solar PV system and you're beginning to save money, have a secured tax free income and are reducing your carbon footprint; but can more be done to maximize the return from your renewable investment?
Do you monitor exactly what you generate? The inverter readouts are not accurate compared to the measurements taken from the generation meter. For that reason, you should only take readings from this standalone meter, not your inverter. There is discrepancy between readings from the inverter and readings taken from the generation meter. The readings taken from the inverter might be out by up to 10% depending on system installed. By installing a retrofit sensor to your generation meter you can gather this information accurately, store it and more importantly, make sense of it.
Why should you monitor what you import and export? Monitoring the mains electricity meter to understand what you import is vital if you are to take better control of your energy usage. Having real time energy use data at your fingertips allows you to understand your current and accumulated energy usage.
Seeing energy in 'pounds and pence' makes much more sense to most of us and allows us to make decisions on when we use appliances, how often and in some cases the best time slots. Tracking what you export also ensures that you utilize the clean energy at the point of generation rather than exporting for a small payment. Better to use the free energy than to buy at 15 pence (average cost per Kwh) from your energy supplier. All this information can be accessed in real time allowing you to make informed decisions if you have the correct system installed.
Do you utilize the green energy at the point of generation? On a sunny day switching your immersion tank on is a good idea. Rather than exporting the clean energy, you are storing it as hot water. Unbelievably up to 70% of generated energy is exported back to the grid with little benefit to the system owner. However technology now exists to make this process simpler and completely automated. Being able to control appliances when you are generating a certain yield is now possible by implementing an intelligent wireless control solution. Retrofit systems are now available to enable better control and utilization of your generated energy at the point of generation.
Use Everything, Export Nothing and Import less! Solutions are now available to allow you to achieve exactly that! Retrofit systems can be easily installed to allow you to intelligently manage your PV system and make best use of the clean energy. Gathering information from the generation meter to accurately measure what you are producing. Accurately monitoring the mains electricity meter along with the flow of energy; gives you a clear picture on your consumption and running costs.
Using this data a system can easily manage smart plugs or switches to redirect energy to appliances utilizing the energy at the point of generation! All this information can be stored on a central display or accessed over the web via a PC, tablet or smart phone. So if you already have a PV plant installed, or are considering on installing one, ensure you have a management system included, it's a nominal additional investment that allows you to truly maximize the return from your renewable investment.
