Amanah Saham Bumiputera (ASB) is one of Malaysia's most beloved investments: stable, Shariah-compliant, and historically reliable. But here is a question more Bumiputera Malaysians are starting to ask: when your electricity bill is high enough, the simple annual return on solar can exceed 10% (for example, about 19% on a RM500 bill), does it still make sense to put every spare ringgit into ASB instead?
This is not about dismissing ASB. It is a well-structured savings product. The question is about opportunity cost, and whether solar belongs in your wealth-building strategy alongside ASB, not instead of it.
ASB: The Benchmark
ASNB (Amanah Saham Nasional Berhad) announces the ASB dividend each year, so we do not quote a rate here: check ASNB's latest announcement. For the comparison below we use an illustrative 5% a year, compounding. Replace it with the rate you expect.
- Return type: Annual dividend and bonus declared by ASNB
- Tax status: ASB income is generally tax-exempt for individual unit holders; check with your tax adviser
- Liquidity: Units can be redeemed quickly
Solar ROI: How Does It Actually Work?
Solar's return is engineering and tariff math. Here is the calculation for a 7.44 kWp system (the size our savings engine matches to a RM 500 bill). Estimate on the RP4 domestic tariff (from 1 Jul 2025), before AFA, the 1.6% RE Fund and service tax; 3.5 sun-hours a day; about 40% of solar used at home and the rest exported and credited at the 27.03 sen Energy Charge (capped at what you import) for 10 years under Solar ATAP; no tariff increases. Your bill and roof will change the figures.
7.44 kWp System Financials (RM500 Bill)
- System cost: RM 17,999 (Solis; Huawei adds RM 3,000, Sungrow adds RM 5,000)
- Monthly generation: about 781 kWh
- Monthly savings (self-consumption + Solar ATAP export credits): about RM 291
- Annual return: about RM 3,492
- Simple annual return: RM 3,492 / RM 17,999 = about 19% a year
- Payback period: about 5.2 years
On a RM 300 bill the same maths gives about 14% a year (5.58 kWp, RM 15,999, payback about 7.2 years); on a RM 200 bill about 11% (5.58 kWp, RM 15,999, payback about 9.3 years). Solar returns are not guaranteed: they depend on your bill, your daytime use and your roof.
ASB's Structural Limit
ASB has a maximum investment limit per account holder (check ASNB's current limit). Many Bumiputera investors who have been saving diligently for years are approaching or have reached this limit.
Solar has no such cap on the investor. You can install a catalogue system sized to your bill and your roof. Solar savings also arrive monthly, through lower bills.
Tax Treatment
- ASB dividends: generally tax-exempt for individual unit holders.
- Solar savings: Electricity bill savings are cost avoidance, not income, so they are not taxed as income for a homeowner.
If you have taken an ASB loan to buy units, the interest you pay offsets your dividend yield, so compare your loan rate with the dividend you expect before borrowing more. Paying for solar in cash, or with 0% instalments, avoids this interest drag.
Wealth Comparison: RM 17,999 Invested
Scenario A: put RM 17,999 in ASB (illustrative 5% a year, compounding). Scenario B: install the 7.44 kWp system. Solar figures: no tariff change, no degradation, export credit counted for the first 10 years only.
| Year | ASB Value (illustrative 5%) | ASB Gain | Solar Cumulative Savings | Solar Savings Less System Price |
|---|---|---|---|---|
| Year 5 | RM 22,972 | RM 4,973 | RM 17,460 | −RM 539 |
| Year 10 | RM 29,318 | RM 11,319 | RM 34,920 | RM 16,921 |
| Year 15 | RM 37,419 | RM 19,420 | RM 46,320 | RM 28,321 |
| Year 20 | RM 47,757 | RM 29,758 | RM 57,720 | RM 39,721 |
| Year 25 | RM 60,951 | RM 42,952 | RM 69,120 | RM 51,121 |
On a RM 500 bill and an illustrative 5% ASB return, solar's cumulative savings overtake the ASB value at about year 8 and finish modestly ahead after 25 years (RM 69,120 of savings against an ASB value of RM 60,951), while ASB compounding means a higher ASB rate would narrow or reverse that gap. On a smaller bill solar's return is lower. The comparison depends on your own bill and the dividend you expect.
The Liquidity Difference
This is ASB's genuine advantage over solar. ASB units can be redeemed within a short time. Solar is a physical asset and you cannot liquidate it the same way. However:
- Solar savings are received monthly through reduced bills, which is better cash flow timing than an annual dividend
- If you sell your home, the system stays with the property; how a buyer values it is up to the market
The Dual Strategy: Do Both
A practical approach is not choosing between ASB and solar. It is sequencing them:
- Install solar (cut your electricity bill and free up monthly cash flow)
- Redirect electricity savings into ASB monthly contributions (you are now funding ASB with money that previously went to TNB)
- Continue topping up ASB up to its limit using the additional cash flow solar creates
In this model, solar does not compete with ASB: it can fund ASB. Your reduced electricity bill becomes part of your ASB contribution.
What About ASB Financing?
Many Malaysians use ASB financing (loans) to invest more than they have in cash. If you are considering this, compare the real net returns: your loan rate against the dividend you expect. If the gap is small, borrowing adds risk for little gain. Check the current figures with ASNB and your lender.
Ready to Calculate Your Personal Solar ROI?
Everyone's solar ROI is different: it depends on your electricity consumption, roof orientation, location, and system size. Use our Solar Savings Calculator to get a personalized estimate in under 2 minutes, or upload your TNB bill to our Bill Analyzer for a precise calculation.
For Bumiputera homeowners who are approaching the ASB limit or looking for their next investment, solar is worth running the numbers on. Our solar packages start from RM 15,999 fully installed (5.58 kWp, Solis). Explore the Solar ATAP program to understand available government incentives before you invest.
ASB and solar are not rivals: they can be partners in a Malaysian wealth strategy. The question is not which one to choose. It is how to make both work together.
