The reason there’s not a simple relationship between battery voltage and state of charge is that your solar system is constantly doing different stuff – electricity is coming and going all the time. However, there is a simple relationship between the two if the battery is disconnected from all chargers & loads and has [...]
"Lead acid batteries should be discharged only by 50% to increase its life" - is an oft used phrase. This means that we should cycle them in the 100% to 50% window as shown below in the Typical state of charge window parameter. So it follows that the usable capacity of a lead acid [...]
Lithium Ion versus Lead Acid batteries In this blog, we will bust the myth that lead-acid batteries are cheaper than lithium ion batteries armed with data. Lithium ion is way cheaper than lead acid batteries and we're going to use battery studies and data sheets to substantiate the claim. We are going to talk [...]
Peukert’s Law and Lead Acid Batteries Note: This blog is for battery enthusiasts. To understand peukert's law and with an intermediate knowledge about batteries and terms like C-rate. Let's talk about the capacity of different solar batteries in real-world circumstances because battery manufacturers are advertising a capacity rating in Ah and a lot of [...]
Why Aluminium makes sense as a rooftop structure for solar plant ? Rooftop Structure: Recently we visited a factory in Tamilnadu where a 100kWp system was installed 5 years ago using MS (Mild Steel) rooftop solar structures. The elements had taken their toll on these structures over the past 5 years and they [...]
In 2017, EcoSoch commissioned a 3.7kWp off-grid project using a Studer inverter with Waaree Solar Panels for our customer at Anekal in the outskirts of Bangalore. Due to rodent issue at this site, the rats were chewing off the cables and causing ground faults which led to a shutdown of the system. As part [...]
On 25/08/2018, EcoSoch commissioned one of its first apartment project for Hemalatha Heights at Bangalore. As part of this case study, we would be comparing the BESCOM bill of this apartment pre & post solar installation. Details of the project are provided below: Description Specifications Capacity 35kWp Modules Waaree 335Wp - 105 modules [...]
Case Study for a Factory Let’s say, your factory consumes 100 units every day between the peak hours of 10 AM to 11AM (1 hour period). Your solar system too produces 100 units during this same period. Assume that, based on your investment, the cost of generating 1 unit of solar energy from [...]
