On-the-spot metering (SSP) is a mechanism that enhances the energy produced by your system and subsequently fed into the grid. Thanks to an economic compensation mechanism between injections and withdrawals, the SSP takes into account all the energy produced: both that fed into the grid and that used for consumption in one’s own home.

The payback time depends on various factors, including exposure, weather conditions and self-consumption. On average, for a photovoltaic-only system it takes 7 years for the return on investment, in the case with accumulation 9 years.

The photovoltaic system is a system that does not require any continuous maintenance, except in the event that you experience a significant drop in performance. In this circumstance it may be necessary to visit a technician to check if there are any problems or if the panels are simply dirty due to atmospheric agents.

Before installation, all modules are subjected to various tests, especially on those that could be the effects of hail.
Thanks to these attentions, normal storm events have a very low risk of damaging your system, except in the case of catastrophic atmospheric events.

Self-consumption runs towards the achievement of savings of up to 50% of the consumption in the bill for a photovoltaic system in ideal conditions of exposure and sunshine, which can reach over 90% with the addition of an energy storage system.
