Investing in a bi facial solar panel system can provide an opportunity to generate renewable electricity from both sides of the panel. When installed in the right conditions, bifacial technology can increase overall solar generation and help property owners make better use of their available space.
However, maximising the long-term value of a bifacial system requires more than simply installing the panels. Careful system design, efficient energy usage, battery storage and regular maintenance can all contribute to better results.
Understanding the Long-Term Value of Bifacial Panels
A bi facial solar panel, more commonly known as a bifacial solar panel, is designed to capture sunlight from both its front and rear surfaces.
The additional rear-side generation can potentially increase the total electricity produced by the system, particularly when the panels are installed above reflective surfaces.
The long-term value of the system will depend on factors such as:
-
Panel efficiency.
-
Rear-side light exposure.
-
Installation conditions.
-
Electricity consumption.
-
System size.
-
Installation costs.
-
Energy prices.
-
Maintenance.
Maximising Solar Energy Generation
The first step towards getting the most from a bi facial solar panel system is making sure the installation is designed correctly.
Important considerations include:
-
Panel orientation.
-
Panel angle.
-
Panel height.
-
Panel spacing.
-
Surface reflectivity.
-
Shading.
-
Available roof or ground space.
A carefully planned installation can help maximise both front-side and rear-side electricity generation.
Take Advantage of Reflected Light
One of the main advantages of bifacial technology is its ability to use reflected light.
The surface beneath the panels can have a significant effect on rear-side generation.
Light-coloured or reflective surfaces can potentially increase the amount of light reaching the back of the panels.
For this reason, the surrounding environment should be considered when designing a bifacial solar system.
Use Your Solar Electricity Efficiently
Generating electricity is only part of maximising the value of your solar system.
Where practical, using electricity while your bi facial solar panel system is producing energy can increase the amount of solar electricity consumed directly.
You could consider running high-energy appliances during periods of stronger solar generation, such as:
-
Washing machines.
-
Dishwashers.
-
Tumble dryers.
-
Other high-energy appliances.
This can help reduce the amount of electricity purchased from the grid.
Add Battery Storage
Battery storage can be a useful addition to a bifacial solar system.
During periods when your panels produce more electricity than your property immediately requires, a compatible battery can store some of the excess energy.
The stored electricity can then be used later when solar generation is lower.
Battery storage can help:
-
Increase self-consumption.
-
Improve energy management.
-
Reduce grid electricity usage.
-
Make better use of renewable generation.
-
Provide greater energy independence.
Monitor Your Solar Performance
Monitoring your system is important for understanding how effectively your bi facial solar panel installation is performing.
Depending on the equipment used, monitoring systems can provide information about:
-
Daily solar generation.
-
Monthly electricity production.
-
Household consumption.
-
Battery performance.
-
System alerts.
-
Historical energy generation.
Regularly checking performance can make it easier to identify unusual changes in output.
Maintain Your Solar Panels
Solar panels generally require relatively little maintenance, but looking after the system can help maintain long-term performance.
Useful maintenance activities include:
-
Checking panels for visible damage.
-
Removing leaves and debris.
-
Cleaning panels when necessary.
-
Checking mounting equipment.
-
Monitoring electricity production.
-
Investigating unexpected performance changes.
With bifacial panels, it is also important to consider the rear of the installation and ensure that unnecessary obstructions are not blocking available light.
Consider the Complete System
The panels are only one part of a solar PV installation.
Other components can include:
-
Solar inverter.
-
Battery storage.
-
Mounting system.
-
Monitoring equipment.
-
Electrical protection equipment.
Choosing compatible components can help ensure that the complete system operates effectively.
Plan for Future Energy Requirements
Your electricity consumption may increase over time.
For example, you may eventually install:
-
An electric vehicle charger.
-
A heat pump.
-
Additional battery storage.
-
More electrical appliances.
-
Smart energy management equipment.
Considering future requirements when designing your bi facial solar panel system can make future upgrades easier.
Evaluate the Total Investment
When considering bifacial solar technology, it is important to look at the complete cost of the system rather than simply the price of individual panels.
Consider:
-
Solar panel costs.
-
Inverter costs.
-
Mounting equipment.
-
Installation.
-
Battery storage.
-
Monitoring equipment.
-
Maintenance.
-
Warranty coverage.
It is also important to consider whether the installation conditions are suitable for generating additional electricity from the rear of the panels.
Choosing a Reliable Solar Supplier
Choosing an experienced supplier and installer can help you get the most from bifacial technology.
A professional solar provider can assess:
-
Available installation space.
-
Surface reflectivity.
-
Panel positioning.
-
Shading.
-
Panel height.
-
Panel spacing.
-
Inverter compatibility.
-
Battery requirements.
This can help ensure that the system is designed specifically around your property rather than using a one-size-fits-all approach.
Bifacial Solar Panels for Businesses
Businesses with large roofs, car parks or suitable ground-mounted areas may be able to take advantage of bifacial solar technology.
Commercial systems can potentially help businesses:
-
Generate electricity on-site.
-
Reduce reliance on grid electricity.
-
Make better use of available space.
-
Support sustainability objectives.
-
Manage long-term energy costs.
The suitability of bifacial technology will depend on the specific site and installation design.
Long-Term Energy Independence
A well-designed bi facial solar panel system can contribute towards greater energy independence by allowing a property to generate more of its own electricity.
When combined with battery storage and efficient energy management, solar generation can become a larger part of a property's overall energy supply.
This can provide greater control over how and when electricity is generated and consumed.
Final Thoughts
A bi facial solar panel system can provide additional electricity-generation potential by capturing sunlight from both sides of the panel.
To maximise its long-term value, it is important to consider the entire installation. Surface reflectivity, panel positioning, shading, spacing and mounting height can all influence performance.
Combining bifacial solar panels with battery storage, efficient energy usage, regular monitoring and appropriate maintenance can help property owners make better use of their renewable electricity and maximise the long-term benefits of their solar investment.
