The photovoltaic system is worthwhile for two simple reasons:
in electricity bill the cost varies between 0.20 and 0.30 € / kwh while the cost of production of the photovoltaic varies between 0.05 and 0.10 € / kwh;
the tax benefits for whose making a plant to their home or company service.
It therefore follows that the energy produced and consumed by a photovoltaic system is always the most savings factor for the user. In general, the amount of electricity produced from the solar energy does not correspond to the amount of electricity used. In particular, the power consumption may exceed the solar production generate in the morning, evening, and during the winter months. Bringing the consumption in peak phases of photovoltaic power generation, it is possible to increase the consumption of electricity self-produced.
The large size appliances can be easily brought into use thanks to a simple instrument such as a timer. Solutions for intelligent management systems, make possible the increase in domestic consumption of about 15%. The use of storage systems (batteries), which retain the excess energy and guide the use when required, may increase this percentage up to 70%.
The cost for electricity for domestic use grew more than 70% over the past 10 years. In contrast, the cost of energy produced from renewable sources is much lower than that purchased from the public network, this means that the more you use photovoltaic energy self-produced, the greater the benefits of your photovoltaic system:
Increased independence from higher electricity prices;
Always lower electricity bills;
More returns from your photovoltaic system.
The most important thing is that the self-produced energy costs will remain stable for years and any increase in electricity prices will increase the profit of your photovoltaic system. In this regard, it is clear that each personal situation is different. The extent of the roof, the number of inhabitants, the time spent at home and annual consumption are all factors that influence the optimal design of the PV system. A self-consumption system can reach up to 70% of battery life.
