After demonstrating the advantages of PV oversizing or overdimensioning and investigating the key factors for success, we now explore the key strategies for making the most of the available solar energy, focusing on the critical roles of the inverter, battery storage, and intelligent energy management. The ultimate goal is to help homeowners achieve greater self-consumption and returns on their solar investment.
Maximizing the cost efficiency of a PV installation is crucial. Homeowners want to recover their investment as quickly as possible. For installers it’s an important argument to win over customers for solar. In this three-part series, we’ll delve into the advantages of PV oversizing or overdimensioning of residential PV installations and focus on the considerations that installers have to take into account.
In the first article of this blog series, we talked about the advantages of PV oversizing or overdimensioning. However, success hinges on key factors like quality inverters, string configuration, and diligent monitoring. In this article, we explore these critical considerations empowering installers to optimize PV systems effectively.
Many small rural municipalities harbor enormous potential for the energy transition. The share of renewable energies can continue to increase if the existing infrastructure is further expanded and modernized. In these municipalities, waste heat and water can also make a bigger contribution to the energy supply.
Right in the heart of Germany there is now a beacon of hope in the form of a PV farm showcasing how cities and local communities can transition to a renewable energy supply. But what makes this project in Bundorf so unique? The PV farm is one of the largest in Germany to involve public participation. Citizens can take part in the project through an energy co-operative and thus collectively drive forward the energy transition in their region.
With the SMA Energy app, system operators always keep constant track of their PV system. They can monitor their system, control loads, or charge their electric car with self-generated electric current from the roof. Now a new update is available.
Our Online Service Centre is designed to make PV system operators and installers’ lives easier. The intuitive platform makes it easier and quicker to create service requests, report issues, register and manage warranties and access the SMA Knowledge Base – at any time of the night or day.
When it comes to power electronics at the module level, the world’s photovoltaic markets are divided. While it is very common for solar technology specialists in the U.S. to install power optimizers (MLPE) in PV systems to meet the relevant installation regulations, these devices are the subject of considerable controversy in the rest of the world. Sweden, for example, has even issued a partial ban on the sale and installation of power optimizers from one major manufacturer because they do not meet the applicable electromagnetic compatibility (EMC) requirements.* So what’s the story with MLPE? What is really technically relevant, and what is just clever marketing? We resolve five common myths about power optimizers.
The first 18 months of field experience with the charging solution SMA EV Charger have shown in Sunny Portal: more than half of the energy used for charging electric vehicles is provided by solar power from your own roof. It is no longer a secret that this allows you to be on the move in a particularly climate-neutral and cost-effective way. But did you know that it means you can even prevent expensive grid expansion and your contribution to the energy transition becomes even more valuable?
When Dennis Halpape and Alexander Krug journeyed to East Africa for the first time with Kassel-based association TOGETHER – Hilfe für Uganda [Aid for Uganda] to install a solar system twelve years ago, there was rarely any light to be found for many kilometers in every direction in the region of Kooki after sunset. Today, when it gets dark, there are significantly more lights on in the houses there.
