Turbine power curve vs. nominal power - how do they relate? In an era of increasing popularity of renewable energy sources, wind turbines play a key role in the global energy mix. To understand the efficiency and performance of these devices, it is useful to take a closer look at two basic terms: turbine power curve and nominal power. How do they relate and what do they mean for turbine performance?...
How to protect a PV installation from arcing? New solution - ArcBox Photovoltaic (PV) installations are gaining popularity as an environmentally friendly and efficient energy source. However, like any electrical installation, they are exposed to various hazards, including arcing. Arcing can cause serious damage to the system and even fires. It is therefore extremely important to ensure ...
Best locations for small wind turbines: Where to site for maximum efficiency Small wind turbines are becoming an increasingly popular alternative as an energy source for homes and small businesses. The increased interest is being influenced by the government's new programme, My Wind Farm. The right choice of location is key to maximising efficiency. There are many locations in Poland where the installation of such...
Priority programme My wind power plant The National Fund for Environmental Protection and Water Management has announced the start of a new programme for prosumers. The aim of the programme is to develop prosumer energy in the area of micro wind power plants or to support the purchase and installation of a backyard wind power plant together with electricity storage. Details of the programme The programme is aimed at owners and co-owners of single-family houses who generate energy...
Photovoltaics, a technology that uses solar energy to produce electricity, is becoming increasingly popular in both private homes and businesses. The green energy produced by photovoltaic modules not only contributes to environmental protection, but also supports energy self-sufficiency, with numerous economic and social benefits. The first step to understanding how photovoltaics support self-sufficiency...
Optimisers or microinverters - what is the difference between the two? The heart of any photovoltaic installation is not the panels, as you might think, but the device that converts the direct current generated by the panels into alternating current that can power household appliances. However, choosing the right technology is not straightforward, as the efficiency of the installation can vary depending on conditions. When...
Which photovoltaic billing system to opt for? Changes from 1 July 2024 From 1 July 2024, the billing rules for owners of domestic solar PV installations will change. New prosumers, i.e. those whose installation comes online after 1 July, will be put on a new model - average hourly price. Existing ones, will have the choice of whether they want to change to the current billing model....
Adding energy storage to an existing PV installation - we look at how! Nowadays, more and more people are choosing to install photovoltaic (PV) panels on their roofs, enjoying the benefits of renewable energy. However, just having a PV installation is only the beginning. Energy storage is also becoming increasingly popular, allowing...
Energy audit compulsory before installing a heat pump! As announced by the Deputy Minister for Climate and the Environment - from 14 June there will be an obligation to carry out an energy audit for those wishing to take advantage of subsidies under the Clean Air Programme for a heat pump. The aim of this decision is to minimise the risk of misguided investments, which in previous years have contributed to unfavourable...
My Current 6.0 after the summer! The President of NFOŚiGW has announced that the 6th edition of the My Current programme will start just after the summer holidays. The next edition of the programme is due to start, once the 5th edition benefits have been paid out. Only when all applications have been processed, can we expect the next intake to start. The "post-holiday" deadline mentioned by the President of the National Environmental Protection and Water Management Authority may therefore refer to September or...
Autoconsumption in photovoltaics - what is it and what does it depend on? Autoconsumption in photovoltaics is a term that refers to the on-site consumption of electricity generated by a photovoltaic system, i.e. directly by a household, business or other entity that has a photovoltaic installation. Autoconsumption refers to the use of electricity produced by photovoltaic panels to power equipment and systems in...
How do weather conditions affect the efficiency of photovoltaic installations? Nowadays, solar energy has become one of the most popular and environmentally friendly energy sources. With the growing interest in photovoltaic installations, it is crucial to understand how to optimise their performance under different weather conditions. Weather and climate have a significant impact on the efficiency of solar panels, so it is useful to know strategies,...
