27. Electrician: A certified professional to handle all wiring for farm buildings, lighting, and pump connections.

Caution Note: An inexperienced electrician may do a poor wiring job that is a fire hazard. They may also overcharge you for materials or use substandard wires. Insist on using only ISI-marked wires and components and ask for an itemized bill.

28. Electrical Material Supplier: A vendor who sells cables, switches, sockets, and other electrical components.

Caution Note: This is an area of significant overpricing. A new landowner may be sold materials at a huge markup. Always get quotes from at least three different suppliers.

29. Transformer/Panel Supplier: For farms that require their own transformer, this is a key vendor.

Caution Note: The vendor may supply a transformer with a lower capacity than what is required, which will lead to frequent power trips. They may also overcharge you for the installation.

30. Solar Panel Installer: A specialist who designs and installs solar power systems for pumps, lights, or even a full off-grid setup.

Caution Note: The solar industry has many fly-by-night operators who use low-efficiency panels or poor quality batteries. They may not provide adequate after-sales service. Only go with a well-established, reputable brand that offers a solid warranty.

31. Biogas Plant Constructor: A specialist who can build a small-scale biogas plant to generate cooking gas and fertilizer from farm waste.

Caution Note: A builder may use poor quality cement and bricks, causing the plant to leak and become non-functional within a year. They may also not design it correctly for your specific needs. Get a written contract with clear specifications and milestones before you begin.
