Optimum tilt angle for fixed panels

By |2020-06-08T10:58:03+05:30June 8th, 2020|

Solar panels generate the maximum output when the sun-light falls perpendicular on the panels. However to achieve the ideal harvest of solar energy, you need to have a multi-axis tracker which throughout the day and throughout the year face the sun and try to maximize the generation. The only disadvantage with such a system [...]

Solar Window Period

By |2020-06-08T10:39:48+05:30June 8th, 2020|

Overview Almost in all meetings, we have noticed that clients require clarification on the placement and orientation of panels. Particularly, clients have pointed out that shadows are falling on panels at 5PM or early morning at 7AM. In this regard, it is imperative upon the EPC to educate the client on the solar window [...]

Criteria for sizing battery banks

By |2020-06-02T22:27:01+05:30April 22nd, 2020|

Solar Battery: Design it right. In solar applications, a lengthy charge time is not desirable since we only have a maximum of 4-6 hours of peak sun each day due to limited daylight and varying weather conditions. To ensure that the batteries receive enough charge, batteries must be adequately sized to prevent deficit charging [...]

Understanding Battery Voltage and SoC

By |2020-06-02T22:32:57+05:30April 21st, 2020|

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 [...]

50% Depth of Discharge for Lead Acid Battery

By |2020-06-02T22:42:51+05:30April 21st, 2020|

"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 batteries are cheaper than Lead Acid.

By |2020-06-18T11:59:58+05:30April 15th, 2020|

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 [...]

Inspection of Solar Rooftop Plant by Solar Care

By |2020-04-14T17:30:32+05:30April 14th, 2020|

Introduction: Solar plant inspection is absolutely necessary once the system is install. It is generally advise to have the system check before plant is commission. We at EcoSoch Solar follow a strict policy of checking all our plant once installed. Solar care is a division within EcoSoch who is responsible for Solar plant Inspection. [...]

Peukert’s Law and Lead Acid Batteries

By |2020-06-02T23:29:58+05:30April 1st, 2020|

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 structure for rooftop…

By |2020-06-09T20:45:58+05:30February 11th, 2020|

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 [...]
