Tips For Increasing Solar Panel Efficiency
- Avoid installing solar panels where trees or nearby buildings may cast shadows on them.
- Install a battery backup to store the excess energy generated for later use.
- Make sure that your energy usage stays within the energy generated. Else you may face voltage drops.
- If your location receives a lot of snow, you can install a warming system to melt the snow off the solar panels.
Final Thought
Even after buying the best solar energy system, you cannot expect it to function with maximum solar panel efficiency forever without constant monitoring. Various factors can bring down the efficiency of the solar panels, the most important being the weather.
Choosing the right panels and method of installation are as important as monitoring their efficiency levels and carrying out periodical maintenance.

Choose Your Panel Wisely
When you go to select your solar panels, the choices you make can affect the efficiency of your solar panels. Monocrystalline solar panels are the most efficient of the three main types, and they are also the most expensive. However, they are also the heaviest ones to install on your roof.
Polycrystalline solar panels are the in the middle when it comes to both efficiency and price, and they were some of the first to be introduced to the public. They are lighter than monocrystalline cells, and also dont create as much waste when being created, so there is less of an environmental impact.
Thin film solar cells are the least efficient, but also the cheapest of the three types. They are also the ones that have the most potential for the future, as there is constant research and development taking place to constantly improve this technology. Its also flexible, and while it takes up a lot more room than the other forms, it is also the lightest one.
Is It Worth Buying Cheap Solar Panels
Solar panels can indeed be expensive, and some will want to find the cheapest solution. Cheap solar panels can make the setup costs more affordable, but they may not be worth it in the long run. After all, investing in solar energy is a decision with long-term implications. Cheap solar panels are likely to have a shorter lifespan and lower efficiency, and for that reason, your savings might be less significant.
When considering installing solar panels in your home, solar panel prices should not be the only factor. It will pay off, in the long run, to invest in high-quality panels and especially in a premium inverter from an MCS-certified installer that has a good reputation in your area.

Solar Panel Efficiency Over Time
The efficiency of a solar panel gets reduced over time. If you installed a solar panel about five years ago, its efficiency is not the same now. As time passes, the efficiency of a solar panel reduces.
The rate at which solar panels lose their efficiency over time is called the degradation rate, and its a natural consequence. The degradation of the solar panel is a slow process it takes a lot of time to lose its efficiency by 1%. In a study, the national renewable energy laboratory estimated that the efficiency of a solar panel loses by 0.5 to 0.8% every year from the installation.
The rate of degradation of the solar panel cannot be avoided, but it can be negligible over a year of time scale because the process of degradation is quite slow. The solar panel efficiency is lost over time mainly due to two reasons.
- Light-induced degradation this will happen only when the panels boron layer is oxidized and partially covers the panel. Due to light-induced degradation, about 1-3% of the panels efficiency may be lost.
- Potential induced degradation this process occurs because of the electrical leakage on the panel due to high humidity and sodium build-up on the panel. It is the rarest situation to have occurred to damage the efficiency.
How Many Solar Panels Do You Need
A 4kW solar panel system would require approximately 16 solar panels with a 250W power output, while a 5kW system comprises 20 solar panels.
As these factors differ from home to home, so it is important to assess each household uniquely.
The first step is to identify your current energy consumption. You measure this in kilowatt-hours , and its important to take the time needed to calculate this as accurately as possible.
- Check your electricity bills to get your power consumption . You can either calculate month by month or add your monthly/quarterly consumption together for an annual figure.
- Decide on how much of your electricity bills you want to cover with your solar panels this can be anything from 10-100%. Your decision will affect the system size and costs.
- Calculate how many solar panels actually fit your roof. An average solar panel takes about 1.44 m2 of roof space. Don’t forget to include at least 30cm from the roof’s edge. Adjust the system size if you realise that you don’t have enough space for all the panels you calculated.

Always Have A Backup Energy Storage System
Solar battery systems are there in the market. There is need to invest in them as they will go a long way through maintaining the total budgets. Solar panel systems such as solar lamps and solar umbrellas usually have their storage facilities, allowing you to save more energy during the daytime.
You can then use this stored energy at night to reduce the high electricity the best thing about us using solar energy is that you can always have power even when faced with a power blackout. The secret is to keep it charged. A backup battery helps in increasing the use efficiency of the solar modules.
Preventing A Temperature Rise
The temperature at which solar systems operate is one key aspect that can affect the quantity of electricity they generate. The majority of people believe that more sunlight equals more power. However, this isnt the case.
Different solar systems react differently to operational temperatures, but in most cases, as the temperature rises, the efficiency of these systems decreases. Remember that the efficiency of a photovoltaic panel is highly influenced by temperature. As a result, you must exercise caution and ensure that there is sufficient space between the roof and the solar panels.
