Frequently Asked Questions

At Madola Energy, we understand that investing in renewable energy and energy-efficient solutions can be a big decision for our customers. That’s why we’ve put together a list of frequently asked questions to help answer any questions or concerns you may have.

Switching to solar can significantly lower your monthly electricity bill, depending on your energy consumption and the size of your solar system. Our team can provide you with an estimate of your potential savings based on your specific needs.

The installation time for a solar system depends on various factors, such as the size of the system and the complexity of the installation. Our team will work with you to provide an estimated timeline for your specific project.

By default, solar panels are designed to switch off automatically in the event of a power cut, unless you have set them up with a backup system. This safety feature ensures that the panels do not feed electricity back into the grid during an outage.

Solar systems generally require minimal maintenance, but we recommend an annual inspection to ensure optimal performance. Our team can provide ongoing maintenance and support for your system.

Excess energy generated by your solar system can be sold back to the grid, depending on your local utility company’s policies. Our team can assist you with setting up a net metering agreement.

Solar panels are designed to last for decades, with a typical lifespan of 25 to 30 years. Our team can provide information on warranties and maintenance to ensure the longevity of your solar panels.

Solar PV cells are made from layers of semi-conducting material, usually silicon.

When light shines on the material, electrons are knocked loose, creating a flow of electricity. The cells don’t need direct sunlight to work, they can work on a cloudy day. However, the stronger the sunshine, the more electricity generated.

Solar PV cells are grouped into modules, and modules are usually grouped into solar arrays. Modules and arrays come in a variety of shapes and sizes.

Most PV systems are made up of panels that fit on top of your roof, but you can also install on the ground, or fit solar tiles.

The electricity generated is direct current (DC), whereas the electricity you use for household appliances is alternating current (AC). An inverter is installed along with the system to convert DC electricity to AC.

Space is a key consideration. 

This roof space will ideally face South, will be unshaded, and at a pitch angle of about 30 or 40 degrees.

East- or West-facing roofs could still be considered, but North-facing roofs are not recommended.

Any nearby buildings, trees or chimneys could shade your roof and have a negative impact on the performance of your system.

Solar PV installations are classed as permitted developments, but always check with your local authority before installing in case there are any limits or restrictions applicable.

The average lifespan of a solar battery storage system is around 5 to 7.5 years for lead-acid and 11-15 years for lithium-ion batteries. However, all batteries are vulnerable if they are over-discharged or exposed to extreme weather.

Solar panels help your business save money by generating
green electricity to be used onsite, lowering your energy demand from the grid during daylight hours and saving you money on energy bills. It will also show your commitment to supporting sustainable energy practices.

Solar is set to become the world’s largest source of power by 2035. Every year that you delay your solar decision is a year that you miss out on the financial and environmental benefits.

Solar PV is easily installed when correctly planned and executed by experienced staff.

Solar PV is generally considered a fit and forget technology as there are no moving parts. Maintenance is minimal and usually consists of a rolling five year electrical safety check to ensure compliance with the latest standards however panels do perform better with annual cleaning in certain environments.

Our capital free option allows you to utilise your roof space to benefit from reduced energy costs without any financial outlay. Through our Power Purchase Agreement (PPA), you receive the benefits of solar a PV solution on an ‘all inclusive’ basis, covering purchase, installation and ongoing operational monitoring and maintenance.

This funded approach also negates the significant tax increases in business rates now being levied against companies who own their solar installation; with a PPA these rates do not apply as the system is not owned by the business, but by us.

In addition, we will upgrade our installations to realise maximum yield and will install batteries where this increases utilisation rates. After all, our interests are fully aligned in generating the maximum possible power from any system. The more power it generates the more CO2 we offset; the more money is saved and the greater the return we realise.

We enter into an agreement to lease the air space above your roof and you receive significantly reduced energy costs, along with the ability to deploy your capital for other business needs.

On a standard roof we can fit between 15‐18w/sq ft. A 50,000sq ft building can support up to 900kWp of solar. This will produce between 751,000kWh in the North of England and 913,000kWh in parts of the South. 

We require between 15 and 25 years in order to realise our long‐term investment savings however we provide break clauses in any year from the 6th year.

There are now over 800,000 solar installations in the UK. The technology is tried and tested and we provide insurance‐backed warranties against water ingress. The mounting equipment is designed to mitigate the possibility of water ingress and we have any number of happy customer testimonials to evidence this not being an issue.

Yes, we can offer re‐roofing / over‐cladding, LED and bird mitigation measures all wrapped into our PPA.

A relatively southern facing roof normally produces more power however an East / West roof can be used and even a Northern roof if the pitch is shallow.

Yes, although lower amounts of power are produced in winter as the sun is lower in the sky, further away and the daylight hours are shorter.

A ballasted roof mounting system is used on a flat or very shallow pitched roof. Structural integrity and loading will need to be considered.

Yes, an uplift in the EPC for the building will be achieved by introducing Solar Panels.

As a safety measure the inverters will switch off during a power cut as it would be dangerous for the Grid engineers to work on a live line.

System size could be restricted by a number of factors including, budget, available roof space, electricity consumption. We aim to provide a Solar PV generation that matches usage however we can also supply the unused power to other geographical sites by way of a ‘sleeving’ arrangement where a business has a large roof and numerous locations.

Quality and efficiency of the panels varies with manufactures. Most reputable installers will only use Tier 1 panels that have an insurance backed warranty.

Generally Solar PV is a permitted development if the array size is less than 1megawatt, not on a national park or on a listed building.

Power generated or yield is determined by five physical factors. Location, pitch, orientation, array size and shading. It can be influenced by weather conditions, cabling loses, and system design. An estimated annual yield(kWh/A) is calculated by using industry standardized software.

We remove & recycle the whole system and leave your roof in pre‐install condition.
