Photovoltaic System on Commercial Roof: Offers & Funding
Commercial roofs offer ideal conditions for photovoltaic systems. We'll show you how to reduce your energy costs and act sustainably with a solar system.
The energy transition is in full swing, and it's not just affecting private households. More and more companies are recognizing the benefits of photovoltaics and installing solar systems on their commercial roofs. However, the path to your own photovoltaic system for your company isn't always easy. This blog post highlights the most important aspects, from planning to offers, funding opportunities, and potential savings.
What You Should Know
A photovoltaic system on a commercial roof offers numerous advantages: reduced electricity costs, contribution to sustainability, improved image, and independence from rising energy prices. However, there are also some special features that differ from systems on residential homes. Commercial roofs are often larger and flatter, which requires a different orientation and planning. In addition, the requirements for statics and fire protection regulations are higher. Before you decide on a photovoltaic system, you should consider the following points:
- Roof Inspection: Have your roof inspected by a professional to assess its suitability. Is it stable enough to bear the additional load of the solar modules? Are there any damages that need to be repaired before installation? The roof pitch is also important – flat roofs are ideal for solar systems, but it must be ensured that water can drain well.
- Analyze Energy Needs: How much electricity do you consume annually? An accurate analysis of your energy needs helps in sizing the photovoltaic system. This prevents over- or under-sizing, which can negatively affect the economic viability.
- System Selection: There are different types of solar modules and inverters. Monocrystalline modules are more efficient but also more expensive than polycrystalline modules. String inverters are cheaper, while optimizers or microinverters optimize the performance of each module individually – particularly useful in cases of shading.
- Permits and Legal Aspects: Find out whether you need a building permit for the installation of a photovoltaic system. Inform yourself about the applicable fire protection regulations and the requirements for the grid connection agreement. Working with an experienced specialist company is essential here.
- Calculate Economic Viability: Create a profitability calculation to determine the amortization period of the system. Take into account the purchase costs, operating costs, electricity cost savings, and possible income from feed-in tariffs.
