Mixing solar panels of different brands is possible, but there are some important considerations to take into account before doing so: Electrical compatibility: It is important that the solar panels being considered for connection have compatible electrical characteristics. This includes power rating (in watts), current and operating voltage. By combining panels with different specifications, it can affect the overall efficiency of the system. Some key electrical issues to consider: Power rating (Wattage): Solar panels should have similar power ratings to ensure consistent performance acros ..read more

In this post we will analyse the characteristics of a 500W solar panel from three major brands in the photovoltaic panel sector: Canadian Solar, Trina Solar and Longi. Their differences will be reviewed, noting the advantages and disadvantages of each one. The models to be studied are: Trina Vertex Solar Panel 500W (TSM-DE18M(II)) Longi Solar Panel LR5-66HPH 500W Solar panel Canadian Solar Hiku5 Mono CS3Y-500MS First, we compare the electrical data of each solar panel. As you can see from the data sheet, the Trina Vertex solar panel has a maximum power voltage (Vmpp) of 42.8V, Longi has 38.3 ..read more

Solar photovoltaic installations without batteries are characterised by minimal maintenance requirements. However, it is advisable to periodically clean the surface of the solar panels. Dirt accumulated on the surface of the solar panels can significantly reduce the energy production of the installation. In the worst case, the impact can be up to 6% loss of production in areas with low rainfall. Water and a brush are recommended for cleaning the solar panels. No chemicals or cleaning products that are not approved in advance by the panel manufacturer may be used. Cleaning solar panels is a sim ..read more

  When we install photovoltaic solar panels we get an energy saving that can change the electrical power needed to use our appliances. In this article we talk about this topic and the advantages of solar energy. Is it recommended to change the contracted power of electricity? Last April happened a record price for the cost of electricity. This caused average bills to rise by more than 11% compared to the previous month and by 28% compared to the same period last year, causing each consumer to pay 7 euros more on average compared to the previous electricity bill. For this reason, mor ..read more

If you are interested in solar energy to save on your electric bill but don’t know where to start, welcome. We will explain in a few simple steps how to find out which installation you need for your home. Attention: The current regulations allow you to compensate for the surpluses of your solar installation that you don’t self-consume and that you pour into the electric grid directly in your monthly bill. From Tienda-solar we recommend this option as the most suitable for the majority of consumers. In this entry we will focus on this case, if it is not yours and you want to tell us your case ..read more

With 2,500 hours of sunshine per year and average radiation of 1,650 kWh/m², Spain has one of the highest natural potentials for the generation of solar energy in Europe. The above-average number of production hours and good infrastructure make the market attractive. Development After the Spanish government suspended the feed-in tariffs in 2013 in response to the euro crisis, the sector initially collapsed. However, as the prices for photovoltaic (PV) modules and battery storage have fallen sharply and Spain’s sun offers high average irradiation, individual plants have already been built in An ..read more
