The high cost of electricity has been felt for some time, all the more so following the increases of recent months. Installing a photovoltaic system is not exactly a joke, it takes specific knowledge in this area, managing the installation safely and taking the right steps to start quickly save on the cost of electricity while helping the environment.
do it yourself possible
When one wants to capture the energy of the sun, the optimal solution is certainly that of a complete (and expensive) installation on the roof of the house, rather than on an adjacent ground. Moreover, the recent DL Energy no. 17 of 2022 has extended the simplification already in place concerning solar photovoltaic (but also thermal) systems to what is necessary for connection to the electricity grid. For the whole operation, no more permits are needed o concession by the municipality, under the recognition of “ordinary maintenance”. Exceptions are cases such as condominium units rather than within a property recognized for its aesthetic and historical value for which relative authorization is required.
Technology also on wheels
The technology applied to solar panels over time has been considerably refined, with greater weather resistance, structural and technological longevity which have made interventions for serene use less complex over the years. Of course, it is necessary to make the best accounts possible to be able to amortize as quickly as possible a significant investment for a complete system, while everything becomes simpler and faster by installing photovoltaic panels on the balcony of the house: there are solutions with wheels for faster movement, you can also hook them to the railing or fix them to the masonry parapet to make the most of the sun’s rays throughout the day.
The balcony solution can become a lot also useful only in case of temporary emergency and power failure, in place of any isolated accumulators (such as backup batteries for computers or other sensitive devices). Rolling transport panels play alternate roles like when you are on vacation by placing them on top of the RV or on the deck of a boat. Fundamentally the approach to balcony photovoltaics at minimum levels provides a single solar panel, which depending on the size and the more or less efficient technology can be from 2.4 kW/h (kilowatt hour) but also only from 1.2 kW/h. In terms of operation, we are in line with that of the panels distributed on the roof, which through a physical reaction induced by light (and the photons that compose it) generates direct current. The latter through a special inverter becomes alternating current ready to be used by any electrical component in the house, no one is excluded.
Stay off the grid
Know that the domestic photovoltaic system can be “on-grid” or “off-grid”. In the first case, it is expected that any surplus accumulation of current in relation to daily needs will be transferred to the electricity network supplier, with a discount on the monthly bill. The condition of “off grid“Is it rather the one in which there is no connection to the industrial energy supply with management in total autonomy. Considering the fact that the balcony photovoltaic system produces a limited amount of direct current, it is very difficult to design one on the network, although it is still necessary contact the energy supply company to activate the meter with the so-called “bi-directionality”. In this way the energy produced by your photovoltaic is not counted in the hourly consumption.
Fighter dear energy
If the energy requirements are very low even a single panel can be considered to meet small needs, such as using a computer, powering a television, interior lighting or powering small appliances. The need for “energy-intensive” equipment is decidedly more critical such as air conditioners and/or heat pumps that would quickly drain the buildup. Sure more panels are installed (obviously due south) and more energy accumulates and it can be tapped, hitting up power for the evening and powering multiple devices together. The cost in this sense is of the order of a few hundred euros to a few thousand, the solutions and offers are not lacking.
Let’s see together some interesting proposals.
