DIY Solar System (A Complete Guide For Beginners) Are you thinking of installing a DIY solar system? While the thought of installing With the necessary knowledge at hand, you’ll be able to design and assemble your own rooftop racking systems or In this guide, you’ll learn about: • Basic electrical rules • Different types of DIY solar systems • Sizing your solar system • Installing racking systems for rooftops or ground mounts • Tilt angle, azimuth angle and panel orientation • Charge controllers and how to size them • Types of battery systems and how to size them • Solar inverters and how to size them • Wire and circuit breaker sizing • Common mistake to avoid 45 days left Things To Consider Before Installing a DIY Solar System By now you’re probably aware of the fact that solar equipment doesn’t come cheap. It would be irresponsible for you to make such a large investment without factoring in all of your calculations and choices beforehand. Some of the key things to consider are: How much energy do you consume each month? First and foremost, establishing your monthly energy consumption is critical. By doing so, you’ll be able to establish the Every home is different – we all consume different amounts of electricity. According to the In order to figure out how much electricity you consume each month take a look at your utility bill. You’ll want to take note of your monthly kWh consumed. Here is an example utility bill: (Example of a utility bill – Credit: Constellation) Lo...

Are you interested in designing an Precursor: Trim Your Power Use You will probably not be surprised to learn that designing a power system to run an off-grid home is not cheap. So it’s extremely worthwhile to consider 1. Figure Out How Much Power You Need This is the most important step, and many people try to skip over it. Don’t! Planning a solar system without knowing how much power you need is like planning a car trip and not knowing how far you are going, and in what vehicle. Ok, now go buy gas for the trip. How much? Well, that depends on your distance and gas mileage. The same is true with solar. You can’t just say “I’m going to buy two absolutely everything that will be powered by your system– remember, if you’re going off-grid, you won’t have grid power to fall back on! 2. Calculate the Amount of Battery Storage You Need Now that you know how much power you need, you need to figure out how many batteries you need to store it. • Think about the weather patterns in your area. How frequently do you get multiple sunless or low-sun days in a row? Your batteries need to be able to get you by during periods when your solar panels are producing well below their maximum. Do you need only enough storage for a day or two, or do you need to have enough batteries to store three or four days (or more) worth of power? • Do you have another power source, like a generator or turbine, that can kick in in a pinch? • Will you be storing the batteries in an insulated room or will they...

Solar photovoltaic system or Solar power system is one of renewable energy system which uses PV modules to convert sunlight into electricity. The electricity generated can be either stored or used directly, fed back into grid line or combined with one or more other electricity generators or more renewable energy source. Solar PV system is very reliable and clean source of electricity that can suit a wide range of applications such as residence, industry, agriculture, livestock, etc. Major system components Solar PV system includes different components that should be selected according to your system type, site location and applications. The major components for solar PV system are solar charge controller, inverter, battery bank, auxiliary energy sources and loads (appliances). • • battery and prevents battery overcharging and prolongs the battery life. • appliances or fed back into grid line. • Battery – stores energy for supplying to electrical appliances when there is a demand. • Load – is electrical appliances that connected to solar PV system such as lights, radio, TV, computer, refrigerator, etc. • Auxiliary energy sources - is diesel generator or other renewable energy sources. Solar PV system sizing 1. Determine power consumption demands The first step in designing a solar PV system is to find ou...

Sizing a In the previous installment of our six-part series on Solar Installer Basics 101 , we provided a detailed overview of how to read a customer’s utility bill . Being able to help customers decipher these statements is often what wins the sale. Equally important, your ability to read these bills is a prerequisite for correctly sizing each customer’s photovoltaic (PV) system for optimal utility bill savings and carbon offsets. Click the image to download the full guide in printable form. This post more deeply explores some of the factors that go into solar PV sizing. Master these steps, and you’ll be able to consistently provide your own clients with the right solar capacity at the lowest price for maximum returns. Understanding Basic Solar PV Sizing Requirements We’ll use California as an example model. However, the basic steps below are the same regardless of location and geography. Let’s start with a hypothetical monthly energy consumption of 500 kilowatt-hours (kWh). This is on the low side for California. But it keeps the numbers simple. Assuming there are 30 days in a month, you can determine a potential solar customer’s average daily energy consumption by dividing their monthly consumption by 30. The formula for this calculation is: Daily Energy Use = Monthly Energy Use / Days in Month 16.7 kWh/day = 500 kWh/mo / 30days/mo Next, we need insolation values. As mentioned in The Beginner’s Guide to Solar Energy , insolation values are reported in kWh/m 2 /day. Sinc...

Sizing Solar Panels – How many solar panels does it take to power your home? Solar energy is the buzz at the moment and many homeowners want to take advantage of the Federal Solar Tax Incentive while it lasts, but how do you know how many solar panels you would need to power your house? Let’s get sizing with step-by-step solar calculations! How Many Solar Panels Do I Need To Power My House Whether interested in installing your own DIY solar power system or or just curious, the first step to energy consumption. These are the things you need to know before sizing your home’s solar system: • What is your home’s annual energy consumption in kWh (kilowatt-hours)? • How much do you pay per kWh of electricity (use this to calculate payback period) • What is the irradiance (sun’s energy) level in your location? • Will your system be grid-tied or off-grid (off-grid needs batteries) • If off-grid, what type of battery will you use (lead-acid or lithium iron phosphate)? • What size solar panels in watts will you use? • Inverters – will you use a central, string or micro-inverter topology (system design) • What are the PV system losses? What size solar system do I need for my home? As a general rule a home solar power system needs 6 solar panels each rated 300 watts with average irradiance of 4kWh/m2/day for every 5kWh of daily energy consumption. The average US home consumes about 30kWh per day and will need 36 Video – How many solar panels do you need for your home? RENOGY are fast ...
