The Role of Solar Charge Controllers in Protecting Batteries and Optimizing System Performance

by vemcoblogs -

If you are a solar PV system owner, you must be aware of the critical accessories that are necessary for the health of your system. One such equipment is a solar charge controller which regulates the charging and discharging of your batteries and also controls the power output. VEMC is the leading solar energy company based in Mumbai and in this blog, we tell you about the role that a solar charge controller plays in protecting and enhancing the performance of your solar power system.

Functions of solar charge controllers

  • Overcharge protection: 

For starters, a solar charge controller protects your batteries from overcharging. As soon as the voltage exceeds the protection voltage, the battery is automatically disconnected. 

  • Deep discharge prevention: 

Converse to overcharge protection, solar charge controllers also prevent deep discharge of your batteries. When the voltage of the battery falls below the over-protection voltage, the solar charge controller turns off the battery output to prevent deep discharge, only to restore the power supply when the battery is recharged.

  • Battery health monitoring: 

A solar charge controller is connected to the same battery terminals and can therefore keep track of the voltage to determine the state of the charge. By constantly monitoring the voltage of the battery, a solar charge controller keeps up-to-date about its health

Types of charge controllers and their suitability

Lets now talk about the two main types of solar charge controllers and the scenarios they best fit into.

  • Pulse Width Modulation (PWM) controllers: 

These are traditional solar charge controllers which operate by connecting directly from the solar array to the battery bank. These controllers are smaller and are suitable only to operate at battery voltage. These must be used with arrays matched with battery voltage.

  • Maximum Power Point Tracking (MPPT) controllers: 

These, on the other hand, are more advanced as compared to the PWM controllers and operate at maximum power voltage. As a result, the output produced is maximized which is great in cold conditions when the voltage of the solar array is much higher than the battery voltage.

Using proper settings for maximum energy harvest and battery lifespan

The right charge controller settings can bring rich dividends when it comes to power output as well as the lifespan of your battery. Different types of batteries work well with different settings. Some of the most important settings that need proper configuration for best results are:

  1. Battery floating charging voltage
  2. Battery over-discharging protection voltage
  3. Battery over-charging protection voltage
  4. Charge controller capacity
  5. Maximum charging current
  6. System voltage

If you’re a solar panel owner, you must make sure you have a quality solar charge controller in place to have maximum harvest and also prolong the working life of your batteries. For more information

The Importance of Solar Energy in Reducing Maintenance Cost of a Building

by vemcoblogs -

Solar energy is one of the most preferred alternative sources of energy. It is especially gaining popularity among Indian users given the abundant sunlight that the tropical country receives coupled with the facility of net metering that allows owners to reduce their electricity bills significantly. But solar energy has a more indirect but significant benefit for your building as well. VEMC is the leading solar energy company based in Mumbai, and in this blog, we tell you how your rooftop solar system can help reduce the maintenance cost of your building.

Reducing wear and tear

Solar panels are installed with either ballasted racking system or roof clamp system, neither of which require you to drill holes in your roof. Rather than damaging your roof, solar panels help protect it by offering an additional protective layer on top of it. They protect the roof from the harsh rays of the sun as well as inclement weather conditions like hail, snow and heavy rains. The overall effect of rooftop solar panels is reduced wear and tear of your roof.

Minimised dependance on traditional energy sources

Energy amounts to a huge cost in maintaining any residential, industrial or office building. Rooftop solar systems help reduce the dependence of your building on traditional sources of electricity. Besides, on-grid solar power systems equipped with net metering facility also help reduce your electricity bills by exporting excessive electricity to the grid.

Simpler maintenance needs

Maintaining your solar panels is quite simple and cost effective. For starters, solar panels sold by VEMC are made of durable material with an average life-span of around 25 years. But the maintenance is quite easy as there are no moving parts and these panels rarely encounter any technical problems being so simple in design. All that is needed is some occasional sprinkling of water and a quick wipe to keep the dust and debris off the panels and enable them to function at peak productivity levels.

Case in Point: Godrej Coliseum

Godrej Coliseum is a mammoth commercial complex located in Sion, Mumbai and provides office space to shipping, pharmaceutical, BPO, auto and telecom businesses. It is spread across an area of around 83 million square feet and offers amenities like escalators, car-parking, fire-fighting systems and advanced security. To power such an enormous commercial facility, VEMC installed mono-crystalline modules and Delta inverters with a total capacity of  75 kW. In coordination with the DISCOM, the facility of net metering was also installed. Post-installation feedback revealed that the client saved upto 1.2 lakh unit of electricity annually which amounted to Rs. 12 lakh.

5 Ways Solar Metering Can Maximise Your Energy Savings

by vemcoblogs -

Whether in domestic, office or industrial setting, solar energy is catching up as one of the most preferred alternative energy sources. The growing efficiency and energy savings offered by solar PV systems across the world have provided further headwinds to this trend. 

VEMC is the leading solar energy company based in Mumbai, and in this blog, we take you through the 5 ways in which solar metering can maximise your energy savings.

1. Lower electricity bills

For starters, installing a solar PV system on your rooftop will instantly cut your electricity bills as the burden will shift away from your grid. Solar panels support a wide range of appliances such as TV,  air conditioners, refrigerator, lights, dishwashers , etc., depending upon their capacity. Users have in fact reported a reduction of up to 90% of their bills.

2. Government incentives

Solar energy is being incentivised by governments across the world owing to its contribution towards a green, carbon-neutral future. Whether in the form of subsidies, tax breaks or other incentives, you can benefit greatly from generating electricity from your rooftop solar plant. VEMC, a leading solar installation company, can also get you more information on the incentives available in your city.

3. Alternative heating system

A significant portion of your electricity is consumed by heating devices like geysers and cookers. The charges that are accrued by running these heating devices can be somewhat neutralised or completely eliminated using solar panels. This is a great way to capture the already available and abundant energy of the sun to heat up your liquids, food or homes, in a clean way.

4. Net metering

Net metering is an ingenious way to sell and keep a record of the excess energy that you export to your electricity grid. In case you do not use all the electricity that your solar panels produce, you can sell the surplus to your local supplier and earn money. At the very least, net metering can enable you to offset your energy bills. All you need is a ‘net meter’ which keeps a record of electricity imported and exported.

5. Higher property value

Finally, solar panels are known to increase property value in the long run. Research suggests that homes with solar panels are also more marketable or put simply, they sell faster! This is a rather indirect, yet significant value that solar panels bring to your property.

When it comes to energy savings, solar PV systems are one of the leading solutions worldwide as they offer a number of ways to cut down on your energy costs. We’ve seen above how they reduce electricity bills and even enable you to monetise your solar PV system through net metering.

Sizing your solar system: finding the perfect balance for your energy needs

by vemcoblogs -

Having a solar power system is a smart way to meet your electricity needs at home and business. However, to make sure that you are able to fulfil your needs without wasting any energy, sizing your solar system is necessary. This allows you to avoid over or underinvesting in your solar system and getting just the perfect one suited for your needs. VEMC is the leading solar panel installation company in Mumbai and in this blog, we tell you how to perfectly size your solar system.

Factors to consider in sizing

  1. Consumption: 

Higher the levels of usage or consumption, more will be the size of the solar power system required. This means a bigger solar power system will be needed in a business or industrial setting as compared to a domestic one.

  1. Location: 

Where you live also impacts the sizing of your solar power system. If you live in a tropical region that gets plenty of sun all year round, even lesser solar panels will produce good amount of energy. However, in temperate regions, you my require bigger solar systems to make up for the low sunlight during the winter season.

  1. Climate: 

Although climate is largely a function of geographical location, some places neverthess are too cloudy or rainy due to other factors like altitude, monsoons etc. If you experience too much of overcast weather during the day, this will also necessitate installing a bigger solar power system.

  1. Efficiency: 

Highly efficient monocrystalline solar panels produce plenty of energy over a limited surface area. This also plays a role in determining the size of your solar system.

A step-by-step guide on sizing

  1. Calculate your usage: 

For starters, you must be aware of your annual energy usage. You can find this from your electricity bill which may also exhibit the peaks and valleys of energy consumption. Find out the average usage of electricity per day.

  1. Find out your peak sun hours: 

The peak sun hours vary according to your location and climate. To make the most of your solar power, find out your peak sun hours using a sun hours chart.

  1. Calculate the size of your solar power system: 

To find out the size of a solar power system that would be most suited for your needs, divide your daily energy requirement (in kWh) by your peak sun hours. This will give you a kW output. Divide this by your solar panel’s efficiency and you’ll get an estimate of the number of panels you’ll need.

Alternatively, if you know the “efficiency factor” of the solar panels (lets say 0.2), here’s the formula to find out the size of your solar power system:

(Daily kWh / Average sun hours) x 0.2 = Size of solar system

Proper sizing of your solar power sytems is very important to ensure optimal performance and cost effectiveness.

10 Solar Energy Hacks for the Next-Generation Solar Power User

by vemcoblogs -

If you own a solar power system, you would want to get the maximum out of it. Luckily, there are plenty of hacks to enhance the efficiency and output of your solar panels. These range from choosing the right type of panel to maximizing their exposure. VEMC is the leading solar power company based in Mumbai, and in this blog, we share 10 solar energy hacks that every next-gen solar power user ought to know.

  1. Use monocrystalline grade A panels

How well your solar panel performs depends a great deal upon the quality of the panels. Monocrystalline Grade A panels are by far the best when it comes to efficiency and productivity.

  1. Increase efficiency using anti-reflection coating

These allow cells to absorb more rays rather than reflect them back. Without these, upto 30% radiation is wasted. 

  1. Get a professional to install your solar panels

Ensure that the installer you have hired possesses the required skills and certifications. Do a background check and find out what others are saying about their past installations.

  1. Ensure the right orientation

In the northern hemisphere, the best orientation for maximum exposure is the geographic south. On the other hand, if you live in the southern hemisphere, it is best to have your panels face the north. If thats not possible, have them face the west as the last resort as this is the direction of the sunset. You can expect more value from energy collected later in the day.

  1. Track the sun with your panels

Trackers enable you to follow the sun as it passes across the sky. While these are most common in commercial solar farms, smaller ones can also be used domestically.

  1. Don’t use too many devices simultaneously

Use your stored power for a longer time period by avoiding too much drain in a short span. As much as possible, stagger your usage over a longer time horizon.

  1. Clean with plain water and sponge 

Dust and debris can block the solar radiation from reaching your panels. To wipe it away, use clean water and a non-abrasive sponge. This will avoid unnecessary scratches on the cell surface. Also, do not use pressure washers to avoid damage. In case there is any stuck-on grime, just use some dish detergent and water.

  1. Use LED bulbs

LED bulbs use at least 75% less energy as compared to incandescent bulbs. By installing LED bulbs in your house or facility, you can reduce energy consumption and prolong the supply significantly.

  1. Use maximum utilities during the day

When you’re using your devices such as dishwashers during the day, you mostly use solar energy. This enables you to avoid the costs of power from the grid.

  1. Use solar power for innovative devices

Besides the usual solar panels, use your solar power in innovative ways. These include having solar cookers, solar geysers, heaters etc. This will allow you to take a huge burden off your conventional supply.
