Grid-Tied Solar System
A grid-connected solar system makes use of solar panels installed on the roof to absorb energy from the sun and convert it to electricity using inbuilt inverters. The electricity generated is then fed to the house for daily use instead of the electricity purchased from the power company. Any excess electricity not used is fed back into the grid with the help of net metering, which gives credits to the customer on their future utility bills. Grid-tied systems are the most prevalent and cost effective, as they do not require solar batteries to store excess energy.
Off-Grid Solar System
As the name suggests, off-grid solar system is not connected to the public electricity grid. Such systems rely entirely on solar energy and are ideal for remote locations with no access to electricity. These systems include batteries that store excess energy for use during cloudy days and at night. Off grid solar system prices are usually higher due to required storage and the installation of additional components such as an inverter.
Hybrid Solar System
Hybrid solar power systems feature both grid connection and storage technology using batteries. This system allows users to store excess solar power for use later when utility rates are higher or when the grid is down. These systems offer increased energy independence and reliability but also come at a higher cost due to the addition of battery systems.
Solar Power System with Battery Backup
Solar battery storage systems are mainly designed to store excess energy produced during the day for use at night or during power outages. This is achieved by using rechargeable batteries which store the energy as soon as it is produced and release it back into the home whenever required. These systems improve energy reliability and autonomy, making them popular in regions with frequent power outages. However, the addition of battery devices now makes these systems more expensive.
Reducing Energy Costs
Apart from their environmental benefits, 6 kw solar system prices are commercially used to reduce electricity costs. Once installed, they provide free electricity to businesses, allowing them to save on utility bills. Over time, these savings can be substantial, especially with rising electricity prices.
Increasing Energy Independence
Generating its own electricity allows a business to become more energy independent and less reliant on the grid and external energy sources. This is particularly important in areas where power outages are common, as a solar system can provide a reliable backup power source.
Enhancing Brand Image
As more consumers prioritize sustainability, businesses that adopt solar energy can enhance their brand image and attract eco-conscious customers. Being a green company can also help attract new clients, as many businesses prefer to partner with companies that engage in environmentally friendly practices.
Tax Incentives and Rebates
Many governments offer tax credits, rebates, and incentives to businesses that invest in renewable energy. These financial incentives make it more affordable for companies to install solar systems and allow them to recoup some of the installation costs. The incentives can be substantial; for example, in the Philippines, there can be up to 30% federal tax credit on solar system costs.
Improving Grid Resilience
Adding more renewable energy sources like solar to the grid helps improve overall resilience and reliability. Solar power can help prevent grid overloads during peak times and provide backup power during outages or emergencies. This enhances the security of energy supply for both businesses and surrounding communities.
Solar Panels
Solar panels, popularly known as photovoltaic (PV) panels, are the components that convert sunlight into electricity using solar energy. They are generally made of silicon-based materials that create an electric field when exposed to sunlight. There are different types of solar panels: monocrystalline panels are made from single crystal structures that tend to be more efficient and space effective. Polycrystalline panels are made from multiple silicon crystals, are affordable but slightly less efficient. Thin film panels are flexible, lightweight and easy to install, though less efficient and requiring more space.
Inverter
Inverters are electronic devices that convert the DC (direct current) electricity generated by solar panels into usable AC (alternating current) electricity for home or commercial use. There are several types of inverters that include string inverters that are used in most residential systems, power optimizers that are paired with each panel and still use a string inverter, and microinverters that convert DC to AC at each panel allowing for greater efficiency and panel independence.
Mounting System
The mounting system is used to secure the solar panels to a roof or the ground and help keep the solar panels at the right angle for optimal sunlight exposure. There are two common types: roof mounting systems are used for mounting solar panels on a building or home roof by attaching brackets and rails to the roof and then securing the panels to the rails. Ground mounting systems are installed on the ground using poles or concrete bases to hold the panels above the ground.
Charge Controller
Charge controllers are used in battery-based solar systems to regulate the amount of electricity generated by the solar panels that goes into the batteries. They ensure the batteries do not overcharge or get drained too low, which can damage them. They come in two types - PWM (Pulse Width Modulation) controllers that are basic and cheaper and come with a lesser charge efficiency, and MPPT (Maximum Power Point Tracking) controllers that are more advanced, expensive and efficient by adjusting the panels' electricity flow.
Batteries
These are optional but included in systems that require energy storage to allow availability of solar power when the sun is not shining, such as at night or during cloudy weather. Lithium-ion batteries are commonly used for solar energy storage because they are compact, efficient and have longer lifespans. Lead-acid batteries are cheaper but bulkier with shorter lifespans. They have two types - flooded lead-acid that requires maintenance and has a lower depth of discharge, and sealed lead-acid (AGM, Gel) that are easier to install with longer DOD.
Energy Needs
To determine their energy needs, buyers should look at their current energy consumption by checking their electricity bills to see how much energy they use on average each month. The average energy use should be calculated in kilowatt hours (KWH) and not in dollars. Buyers should also assess their future energy needs and determine whether they are likely to increase energy usage in the near future due to expansion, installation of new energy consuming appliances, etc.
Roof Suitability
Buyers should assess the suitability of their roof for solar panel installation by evaluating the roof type, angle and space. They should determine whether their roof is flat, sloped, or made of asphalt shingles, metal or other materials, as different roof types will require different mounting systems to install the panels. They should also evaluate whether there is enough space to install enough panels to meet desired solar energy needs. A buyer's roof should be large enough to allocate 100 square feet per solar panel. In addition, the condition of the roof should be evaluated to ascertain whether it is strong enough to support the panels. If they plan to install the solar panels on a ground mount system, the ground should be flat and free of obstacles like trees, boulders or buildings that may cause shading.
Solar Incentives and Cost
Buyers should research the current solar incentives available in their location that can help them lower the installation costs, such as federal or state tax credits or local rebates. They should also get price quotes from different installers to compare prices and ensure they are getting the best deal.
Installation Experience
Buyers should ensure they hire only experienced and reputable installers to ensure proper installation. They should evaluate the installers' experience by researching how long they have been in business, whether they use subcontractors or their own employees, and how many solar installations they have completed. In addition, they should only offer solar power systems to professional teams to ensure proper installation.
Solar System Maintenance
Buyers should purchase easy to maintain solar power systems in order to easily maintain them. They should also ensure they understand the type of maintenance required for different types of solar power systems and whether they will be able to complete it or will need to hire professionals.
A1. The price of a 6 kW solar system in the Philippines is generally based on the components used, system type, and the complexity of the installation. Other factors that may influence the price include the roof type, whether the system will use microinverters or optimizers, permits, fees, and labor.
A2. A 6 kW solar system can potentially power an entire home if it is energy efficient and solar system buyers avoid high energy consuming appliances during peak daylight hours. A 6 kW solar system generates around 600 KWH per month, which is enough to power an average energy-efficient home that does not rely heavily on using air conditioning or electric heating.
A3. A 6 kW solar system is worth it for homeowners who want to significantly reduce their electricity bills and hassle payments for utility power. A 6 kW solar system also provides protection against future electricity rate increases.
A4. On average, it takes three to seven years to break even on solar panels. Buyers will break even faster if they live in areas that offer high solar incentives and are able to secure low financing rates.
