: Hospital and Clinic Project Experience :
Gorkha Hospital
Gorkha hospital is located in the Gorkha region of Nepal, the hospital is close to the main city and connected to the metro-grid but does not have reliable power and relies heavily on Diesel Generator. The project was scoped and designed by the Alternative Energy Promotion Centre (AEPC) to implement an AC coupled PV system which could power critical loads during day time directly from PV with some storage to cover night-time loads and delivery some autonomy.
The project was executed as a JV between Sunshine Energy and Peak Power and we delivered the system based around Victron Energy Quattro platform and SMA AC coupled PV inverters. Once the system installation was completed, there was an extensive re-wiring process to integrate the inputs and outputs from the renewable-based power system into the existing hospital electrical network. This system had some technical design gaps which we were able to address during the project and work through with the Hospital engineering staff. The result was a better integration of the grid and generator inputs with a full system bypass, as well as extensive distribution network rewiring and rebalancing.

Raskot Hospital
Raskot Community Hospital, a not for-profit based in the remote Kalikot region of Nepal. It has been around for more than ten years and is going through a sustainability uplift program which involves implementation of a hybrid solar based power system which can provide clean and reliable energy to reduce reliance on diesel generators, improve power quality and reliability.
Peak Power/Motherland Energy Group delivered this project to implement the power system at the Hospital, this is based around the Victron Quattro platform with SMA AC coupled PV, the integration and control system are based on Victron’s GX platform and Peak Power fabricated switch boards.
This system integrates with the existing diesel generator at the site, although this was not included in the scope of the design, we chose to integrate the diesel generator to improve overall system reliability and performance.

Dhulikhel Hospital Outreach Centre - Bahunipati
The Bahunipati clinic services the local region where grid is unreliable but not as bad as some of the other clinics, it is almost impossible for a clinic to run any medical or IT equipment in these locations so reliable and clean power is a must.
For this site which was one our first with Dhulikhel Hospital the budget determined SMA AC coupled PV with battery inverter, battery bank consisting of 48v 200AH 12v cells, we included our custom switchboard which has bypass, surge protection and low impedance earthing.
We also re-wired existing distribution wiring to enable protected loads circuits and grid fed circuits, with all essential lighting and equipment be moved to protected loads. Although these solar PV systems made a tremendous difference to the clinic being able to service the public the lack of budget really limits the impact we could have on the clinic.

Dhulikhel Hospital Outreach Centre - Phalebas
The Phalebas clinic services the local region where grid is horrible, it is almost impossible for a clinic to run any medical or IT equipment in these locations so reliable and clean power is a must.
For this site the budget determined SMA AC coupled PV with battery inverter, battery bank consisting of 48v 200AH 12v cells, we included our custom switchboard which has bypass and surge protection and low impedance earthing.
We also re-wired existing distribution wiring to enable protected loads circuits and grid fed circuits, with all essential lighting and equipment be moved to protected loads. If the battery SOC is low, the system can be connected to grid, however these remote sites always have high impedance connections so in reality you might be lucky to get 180v and a couple of amps out of it. This is why designing system to be sustainable with PV and Battery is essential, unfortunately budget dictates the design.

Dhulikhel Hospital Outreach Centre - Manekharka
The Manekharka clinic services the local region where grid is almost useless, it is almost impossible for a clinic to run any medical or IT equipment in these locations so reliable and clean power is a must.
For this site the budget determined SMA AC coupled PV with battery inverter, battery bank consisting of 48v 2v cells, the site had a much cleaner distribution system than others similar clinics so we installed simple bypass option with a small switchboard, quality breakers and SPD’s.
We also re-wired existing distribution wiring to enable protected loads circuits and grid fed circuits, with all essential lighting and equipment be moved to protected loads. This system is a lot more reliable and robust due to the battery bank design and capacity. We also completed a PV extension at this site to increase the solar and PV inverter capacity at the request of the clinic. This system was reliable and works very well for the clinic.

Dhulikhel Hospital Outreach Centre - Dorpu
The Dorpu clinic is in a very remote region, it is difficult to travel and access this site requiring a 12-hour car journey over rough roads ... but the location is amazing. The local grid conditions are interesting, the site is very near to a large Hydro power station which provide clean but unreliable power.
We also re-wired this building extensively as the wiring in the building was extremely badly done not to mention missing earth to all circuits. We also ran 3 phase circuit for the x-ray machine. Although the site has close proximity to the Hydro station the grid connection was high impedance and almost impossible to synchronise with.
We did not recommend this design to Dhulikhel Hospital at the time due to the requirements of the loads on the batteries, not to mention the remoteness of the site and the cold winter would be tough on those batteries, unfortunately the budget was not flexible to scope 2v deep cycle batteries which would have been a lot better.

Druk Pema Karpo Dental Clinic
The dental clinic is one small faculty within the Druk Pema Karpo Clinic at the rear of the Druk Amitabha Mountain in the Ramkot area just outside of the Kathmandu valley. This is a very quiet and peaceful place where the electrical grid isnt great and running generators was the last thing the staff wanted to do.
The renewable energy system is designed and integrated into the dental clinic to supply a critical loads panel which powers the essential items in the clinic such a chairs, x-ray, compressors, IT equipment and so forth so that the dentists can continue treatment completely uninterrupted. The system is completely silent and can handle the large inrush demands of compressors and autoclaves.
The system is also integrated into the overall electrical management system at the site to enable monitoring and power control for the nuns who maintain and keep the system healthy.
