You will not have power available during a blackout. The grid connect inverter will automatically shut itself off within a few milliseconds of a blackout. This avoids the potential of a dangerous “brown-out” in your home and to prevent back feeding into the grid. If you want to keep having electricity available during a blackout then you would need back up batteries. This will add to the cost of the system.
The strength of the solar energy (radiation) available depends on the time of year, the time of day, and the latitude of the generation point. The amount of energy that the system generates can change due to:
In grid connect systems, any subsequent power will come from the main’s grid.
Yes! Due to the lower hours of sunlight during winter there is an effect, however, by installing the units correctly and with solar systems relying on sunlight and ultraviolet rays, not heat, you will not notice the difference. In Summer with longer hours, is when surplus power is more readily produced.
Yes! For example, a system with solar panels facing in a southerly direction will generate far less than one with a northerly aspect. However, east/west installations can be a good option depending on the installation scenario.
Usually the inverter goes alongside the fuse box. The inverter is silent and has a display to show the electricity generated. Other data options such as total electricity generated since installation are available.
Yes. You can get additional solar panels at any time to increase generating capability but you might have to upgrade to a larger inverter. Alternatively you could purchase a larger inverter when installing the system initially and then plan to add some extra solar panels later.
Not always. A 3 phase inverter directs power across all 3 phases evenly, however you can also have a standard inverter and not adversely affect your returns because your new digital meter will usually reconcile the power across all three phases in 15 minute increments. Whether or not you need a 3 Phase Inverter really depends on the size of your system, your load, and usage profile, and future plans so please contact our solar staff so that we can assess what you have in your home and then provide you with the right information.
Solar panel systems are made of durable tempered glass and require little to no maintenance for the 25 to 35 years that they will generate power. In most cases, you don’t even need to clean your solar panels regularly. If something does happen, most equipment manufacturers include warranties.
(there was no number here on the website, needs to be filled in) KW solar system needs approximately 10m2 on your roof, a 1.5KW system needs approximately 15m2, and so forth.
