Does solar work when its cloudy?

Do Solar Panels Work When It’s Rainy Or Overcast?

Solar panels produce the most electricity on days with clear skies and plentiful sunshine. But all is not lost on cloudy days – typical solar panels can generate anything between 10-25% of their estimated capacity. The amount will vary depending on the type of solar panel as well as the cloud coverage. Modern PV systems actually function better in cooler temperatures.

UV light also reaches the earth’s surface even when it’s cloudy. Have you ever gotten a sunburn when it was overcast? Then you have firsthand experience of this. Even during the grayest days, visible light still gets through clouds and rain. Whether it’s cloudy or foggy outside, even the most standard solar panel will produce some power during daylight.

What if you live in a place where it’s mostly overcast?

If you’re thinking about investing in solar panels to help you save money on your electricity bill, you need to examine how much sunshine you receive annually and not on a specific day. In South Africa, however, we have an abundance of sunshine and while the winters in the Western Cape might get a little dreary, the amount of daylight is still enough to make solar power a legitimate option.

Another option is to invest in solar batteries. They can help you save money by storing free energy to use on cloudy or rainy days.

Even in places like Germany where it can be grey throughout most of the year, they have successfully installed approximately 25 gigawatts of solar power. This accounts for 50% of their electricity needs. The UK is not far behind and has experienced enormous success with its solar initiatives.

Overcast days will come and go, but on average, it won’t affect the ROI of solar panels. If you would like to find out more about saving on electricity bills even when it’s cloudy or rainy out, speak to the team at Nupower today.

Need a personalised, affordable renewable energy solution that will last well into the future?

Unless you are an expert in your own right, when you choose to move over to renewable energy, you are going to want a team like NuPower Solar to offer you sound, knowledgeable advice that will lead to the installation of a solar system that will last well into the future, pay itself off quickly and leave you with nothing but the benefit of free hot water or power for life.

Taking a look at the advances in technology and the increasing manufacturing scale of photovoltaic (PV) products, it is clear that PV systems have increased in efficiency, which has also led to a cost reduction in PV installations throughout the world, and that includes sunny South Africa!

NuPower Solar uses only Victron Energy PV components in their installations, and with these award-winning European products added to NuPower products, you can be absolutely certain of a quality installation that will most definitely stand the test of time, and every kind of weather!

Looking around at many of the new residential properties, developments and other commercial buildings going up with solar panels at a speed that belies the economy, it is clear to see that renewable energy is the way of the future in South Africa, working in tandem to save property owners money, add resale value to their investments and to protect the environment from the foundations up.

Unfortunately, Eskom is very reluctant to let go of its grip on high end electricity users, because they are the ones who in actual fact subsidise electricity supply to low-income households, and, added to massive amount of money lost through corruption, Eskom is going to hang on as long as possible because they need the money now more than ever to support and upgrade their wobbling infrastructure!

The more high end electricity users that invest in solar systems, the more the same low-income households are going to pay for their own power, it is a vicious cycle that will keep going until Eskom gets its act together on a myriad of levels and sets up a workable system that will include feed-in-tariffs, as the majority of the world already does!

It’s actually really sad to think that Eskom has such a stranglehold on South Africans as the only electricity supplier, (and major supplier of income for the government!) that renewable energy is being held back at a time when it has become a vitally important contribution to the health of our environment, and bringing well-deserved financial relief to home owners and commercial property owners, based solely on domination and greed.

Cape Town is the only place in South Africa that has managed to squeeze out some form of selling electricity back to the grid, but it is still nowhere near the standards seen around the globe.  The good news is that there are solutions that NuPower Solar is able to offer that will still make a major difference to your electricity bill with PV installations!

If you are living in an area with no access to the grid, or have the financial means to replace Eskom completely, an Off-Grid PV system that offers superior efficiency and long life expectancy is the way to go, and NuPower has the expertise to design and install off-grid systems that can vary from a few hundred watts to several hundreds of kilowatts in size.

Grid-Tied PV systems are the most popular and affordable solar systems being used for commercial, industrial and large residential use, offering the most efficient application for those whose highest energy use is during sunshine hours.

If you are looking at great Back-up power solutions, which charge batteries from Eskom in order to keep the lights on when there are power outages, NuPower will assist you in putting together the perfect system to run as much power as you need during blackouts.

Although the head office is based in Gauteng, NuPower is a national company that has dealer networks spread throughout South Africa in order to provide outstanding service to clients from the Western Cape to Kwazulu Natal and everywhere in-between!

Just give the team a call and let them take it from there to offer you renewable energy solutions that will suit your power requirements perfectly, at affordable prices! The team at NuPower is a pleasure to work with! They are passionate about the difference the over 12 500 solar systems already installed by this team has made, which has also earned them many satisfied clients over the years, and at the same time mirrored their absolute commitment to a greener South Africa!

NuPower Solar uses award-winning Victron Energy products in their personalized energy solutions.

NuPower Solar is at the forefront of growth in the use of solar energy in the domestic, commercial and industrial sector throughout South Africa, a leadership position which has been earned through the ability of the NuPower Solar team of experts to deliver outstanding custom solar solutions to suit a variety of applications.

Yet another aspect of the success achieved by NuPower Solar after many years in the industry is that the quality of products offered by this team is of an award winning standard, such as the Victron Color Control (CCGX), which provides intuitive control and monitoring for all Victron power systems.  The list of Victron products that can be connected to the Victron Color Control (CCGX) by NuPower Solar is endless, covering everything from inverters, Multis, Quattros, MPPT solar chargers, BMV battery monitor, Lynx Ion and more.

As a team that remains on the cutting edge of developments in the solar industry, and one committed to ongoing investment into research and development, it stands to reason that NuPower Solar is proud to provide clients with solar solutions that use only the best of products available on the market.

As recently as June 2017, Victron Energy won the 2017 European Battery Management Systems Product Leadership Award, which assures every NuPower Solar client that any solar system designed and installed by NuPower is of the highest standard possible.

Victron products are used by NuPower Solar when designing Off-Grid PV systems, which are for use in areas where there is no access to the grid, Grid-Tied PV systems, which, because there are no batteries, are perfect for commercial, industrial and large residential use, where the most efficient use is for applications where the highest energy use is during sunshine hours.

Back-up power solutions designed and installed by NuPower using Victron Energy products use Eskom power to charge batteries, which are then used to supply the connected load when power goes out, and, once the power is back on, the battery bank is recharged within a few hours.

Service excellence backed by superlative products and an in-depth expertise in the field of solar energy are just a few of the benefits you can look forward to when you contact NuPower Solar for a personalized energy solution!
