How to make a violin at home. In this post, I would like to guide you through all the steps I followed to make a violin. Then I’ll share with you the reason I built this, my experiences, what Kept me moving forward when I lost confidence, and some of my mistakes which you are advised to avoid, and then I will answer some frequently asked questions related to violin. Let’s get started. This blog is all about renewable energy projects. However, every once in a while I do some hobby projects. This year I got a chance to join a violin class with my friends Sanal and Aswin. And guess what, we joined an institute. Check this on Amazon https://amzn.to/3ufFjI8 When I got this chance to hold these amazing musical instruments in my hands I felt a strange inspiration to make one of them. Even though I am not good at woodworking and acoustics I decided to give it a try. But I had no idea, where do I begin.

Hi, this is New Physicist again. Today we are going to learn about three different types of solar power systems. We all know that solar power is gaining more and more attention these days. In the past, solar power system components were very expensive but recent technological developments have made a drastic reduction in the cost of solar power components, mainly solar panels and batteries.
By installing solar power systems you can reduce your electricity bills. But there are different types of solar power systems that you can adopt for your property. You can decide which one is suitable for you after learning about them. Let's get started.
Different Types of Solar Power Systems
1. Off-grid Solar Power system
AC based Offgrid Solar System
An off-grid solar system is a stand-alone unit that is not connected to the electricity grid. These systems are typically remote where the cost of running a utility connection is more expensive then purchasing an off grid solar system.Off-grid Solar Systems work by generating electricity from solar panels and using it to charge a solar battery via a charge controller. An inverter converts the direct current(DC) to alternate current(AC) so that it can power your home or business appliances. Excess solar power charges your solar battery so that you can use the electricity at night or during times when your system is not generating power.
DC-based Solar Power System
In a DC system as the name suggests the entire system is DC based, but still there is no grid connectivity. Its basic components would be a solar panel, solar charge controller, batteries and DC load. There isn’t any DC to AC conversion here. But the property's wiring has to be properly designed to handle a DC current. The Advantage of a DC based system is that they do not need an Inverter, because all equipments are running on DC. So we can save money as well as energy since there's no DC to AC conversion loss.
2. On-Grid Solar Power System
This system works in two-ways — the supply of electricity can flow from the grid to which it is connected to the user’s home and from the user’s home to the grid. This feature makes the on-grid solar system affordable and highly useful. The solar panels, installed on the user’s home are ‘tied’ to the grid. The solar panels convert sunlight into electric energy, which is Direct Current (DC). This current is then sent to an inverter. The solar inverter then converts the DC to Alternating Current (AC), thus making it power the electrical items. This electricity is then routed to the grid where it is supplied for day to day use.
The grid-tied inverter additionally regulates the amount and voltage of electricity fed to the household since all the power generated is mostly much more than a home needs or can handle. An important feature is a net meter. It is a device that records the energy supplied to the grid and the energy consumed. At the end of each month, the outstanding is recorded and the consumer is provided with a bill. This ‘converted’ power supply is then used by homes through the main electricity distribution panel.
3. Hybrid Solar Power System
Hybrid solar systems generate power in the same way as a common grid-tie solar system but use special hybrid inverters and batteries to store energy for later use. This ability to store energy enables most hybrid systems to also operate as a backup power supply during a blackout, similar to a UPS system.
In the solar world, the term 'hybrid' refers to a combination of solar and energy storage which is also connected to the electricity grid. Hybrid solar systems utilize battery-based grid-tie inverters. These devices combine can draw electrical power to and from battery banks, as well as synchronize with the utility grid.
