A site analysis helps determine what you can achieve with a photovoltaic system. We propose solutions depending on a variety of factors.
With full independence, your photovoltaic installation will generate all the electricity that you need. A battery storage solution ensures that the energy is available when you need it.
There are a number of variations for partial independence.
For example: A solar module installation without an energy storage solution generates electricity during the day, providing you with power and sending any surplus back into the grid system.
Or, your roof installation is not able to generate enough electricity to meet your needs all year round.
Probably the most common type of installation: using your solar modules to generate electricity and store it in a battery.
Once the battery is full, any excess energy is directed into the network via the feed-in tariff. Utilize the stored energy when the installation is not producing any power, usually overnight, and should the battery become fully discharged, your additional needs are taken from the regular grid system.
Storing the generated energy in batteries is becoming the preferred choice of installation type.
There are different options here – a standalone battery, or a hybrid solution where the battery and inverter and combined into a single unit.
The hybrid approach is more compact, so if space is an issue this could be the solution for you.
There are also different types of battery storage, the most common is lithium batteries, but an alternative is to use salt batteries.
Charge your electric vehicle overnight using the stored energy generated during the day from your rooftop solar installation.
If you have space, you may want to consider a solar carport in addition to a rooftop installation.
Is your roof suitable for solar modules? We can check to determine the best solution for your needs.
The underlying structure of your roof should be in good condition. If in doubt, it should be checked by a roofing professional prior to installation.
If you have a flat roof, you have a number of choices regarding the type of installation and the direction of the modules.
Perhaps the biggest factor for a sloping roof is its orientation toward the sun. This will influence the optimal performance of your solar installation.
If you have both a sloping roof and also an area of flat roof then a combination solution is also a possibility.
Are there any features on your roof that need to be taken into account such as chimneys, roof windows etc? These need to be factored in to the overall project.
The orientation of your roof can influence to performance of your solar installation.
The most effective is a south-facing roof, or an east-west facing roof.
Where and how many solar modules should you install? This comes down to your preference, surface, budget, and energy needs.
On-roof solutions are the most common type of installation. A typical installation for a single family home usually takes just a few days.
In-roof systems take over the sealing function of the roof and therefore save on the cost of tiles.
But perhaps the more significant difference is that an in-roof solution provides a more attractive appearance.
The one-off cost is slightly higher compared to an on-roof solution. For those for whom appearance is important, the in-roof system is the better choice.
A solar carport provides a perfect solution for charging your electric vehicle.
When combined with a rooftop photovoltaic installation, it can increase the amount of energy available for use in your home.
A solar balcony is a great way for apartment owners to reduce their energy costs.
Do you live in a multi-family apartment block, or a group of houses with a common area such as a parking garage?
PG Solar can advise you on how to form a solar community, including the billing process for sharing the solar energy produced by your building complex. Contact us for more information.
Use an online calculator to receive an indication of how much energy your roof could generate and an estimate of the cost of the solution.
You can also obtain a detailed quote (on request) that would provide specific photovoltaic modules, inverters, and battery storage components as well as the additional installation materials that would be required.
Where and how many solar modules should you install? This comes down to your preference, surface, budget, and energy needs.
You should be able to get a one-off subsidy from the state based on the production capacity of your installation. The application documentation for this subsidy, which we prepare on your behalf, is normally paid to you one to two years after applying.
Depending on where you live, there may also be additional incentives available depending on which canton and community you live in. Again, PG Solar can help you find out and support your application process.
Your local electricity network provider should provide a feed-in tariff – payment or credits for any energy that your installation passes into their supply network.
PG Solar can also provide you with details of the tariffs available to you.
You should be able to offset some installation costs against your income tax declaration.
PG Solar offers a referral scheme which provides you with a cash bonus every time you refer somebody for a photovoltaic installation. The amount to paid out depends on the estimated production capacity of the installation and is paid out once the referred customer installation is completed. There is no time or quantity limit on how many referrals you can make.
Our referral scheme is open to anyone. You do not need to have an installation done by us in order to benefit. Register with us for details of the scheme and begin to earn cash rewards.
Once you agree the offer for your photovoltaic installation, our project managers will establish an installation schedule based on the availability of the materials.
You will be kept informed about the status of your project – availability of components, and the planned start date. In the event that there will be bad weather on the planned start date, we will advise you as early as possible about this and the rescheduled installation date.
Once the installation is completed, our team will commission the configuration and ensure that it is all working correctly.
You will be given instruction on how to use the application that shows you the performance of your installation.
If you have agreed to remote monitoring, our team will also activate and check that this is operational.
With your permission, PG Solar will monitor your installation remotely, keeping an eye on it’s performance and detecting any issues that might arise.
With an optional maintenance contract, you can ensure maximum performance of your installation with annual service checks and preventative maintenance.
How will your photovoltaic installation contribute to a sustainable environment? Will it reduce your home’s CO2 emissions and carbon footprint?
A photovoltaic installation reduces reliance on fossil fuels for your energy needs and at the same time you are reducing your carbon footprint.
Request a detailed offer from us that will include an estimation of your contribution to the environment.
Through our partner program with Almighty Tree, your photovoltaic installation will help with the regeneration of Switzerland’s forests. For every 5kWp of solar modules installed, PG Solar commits to planting a tree with Almighty Tree.
